Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2016-10208

Sergej Schumilo and Ralf Spenneberg discovered that a crafted ext4 filesystem could trigger memory corruption when it is mounted. A user that can provide a device or filesystem image to be mounted could use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-8824

Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-dccp.conf install dccp false

CVE-2017-8831

Pengfei Wang discovered that the saa7164 video capture driver re-reads data from a PCI device after validating it. A physically present user able to attach a specially designed PCI device could use this for privilege escalation.

CVE-2017-12190

Vitaly Mayatskikh discovered that the block layer did not correctly count page references for raw I/O from user-space. This can be exploited by a guest VM with access to a host SCSI device for denial of service (memory exhaustion) or potentially for privilege escalation.

CVE-2017-13080

A vulnerability was found in the WPA2 protocol that could lead to reinstallation of the same Group Temporal Key (GTK), which substantially reduces the security of wifi encryption. This is one of the issues collectively known as 'KRACK'.

Updates to GTKs are usually handled by the wpa package, where this issue was already fixed (DLA-1150-1). However, some wifi devices can remain active and update GTKs autonomously while the system is suspended. The kernel must also check for and ignore key reinstallation.

CVE-2017-14051

'shqking' reported that the qla2xxx SCSI host driver did not correctly validate I/O to the 'optrom' sysfs attribute of the devices it creates. This is unlikely to have any security impact.

CVE-2017-15115

Vladis Dronov reported that the SCTP implementation did not correctly handle 'peel-off' of an association to another net namespace. This leads to a use-after-free, which a local user can exploit for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the sctp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-sctp.conf install sctp false

CVE-2017-15265

Michael23 Yu reported a race condition in the ALSA sequencer subsystem involving creation and deletion of ports, which could lead to a use-after-free. A local user with access to an ALSA sequencer device can use this for denial of service (crash or data loss) or possibly for privilege escalation.

CVE-2017-15299

Eric Biggers discovered that the KEYS subsystem did not correctly handle update of an uninstantiated key, leading to a null dereference.
A local user can use this for denial of service (crash).

CVE-2017-15649

'nixioaming' reported a race condition in the packet socket (AF_PACKET) implementation involving rebinding to a fanout group, which could lead to a use-after-free. A local user with the CAP_NET_RAW capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-15868

Al Viro found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of the second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16525

Andrey Konovalov reported that the USB serial console implementation did not correctly handle disconnection of unusual serial devices, leading to a use-after-free. A similar issue was found in the case where setup of a serial console fails. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16527

Andrey Konovalov reported that the USB sound mixer driver did not correctly cancel I/O in case it failed to probe a device, which could lead to a use-after-free. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16529

Andrey Konovalov reported that the USB sound driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16531

Andrey Konovalov reported that the USB core did not validate IAD lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16532

Andrey Konovalov reported that the USB test driver did not correctly handle devices with specific combinations of endpoints. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16533

Andrey Konovalov reported that the USB HID driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16535

Andrey Konovalov reported that the USB core did not validate BOS descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16536

Andrey Konovalov reported that the cx231xx video capture driver did not fully validate the device endpoint configuration, which could lead to a null dereference. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16537

Andrey Konovalov reported that the imon RC driver did not fully validate the device interface configuration, which could lead to a null dereference. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16643

Andrey Konovalov reported that the gtco tablet driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16649

Bj&oslash;rn Mork found that the cdc_ether network driver did not validate the device's maximum segment size, potentially leading to a division by zero. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16939

Mohamed Ghannam reported (through Beyond Security's SecuriTeam Secure Disclosure program) that the IPsec (xfrm) implementation did not correctly handle some failure cases when dumping policy information through netlink. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-1000407

Andrew Honig reported that the KVM implementation for Intel processors allowed direct access to host I/O port 0x80, which is not generally safe. On some systems this allows a guest VM to cause a denial of service (crash) of the host.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.96-2. This version also includes bug fixes from upstream versions up to and including 3.2.96. It also fixes some regressions caused by the fix for CVE-2017-1000364, which was included in DLA-993-1.

We recommend that you upgrade your linux packages.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The usbhid_parse function in     drivers/hid/usbhid/hid-core.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (out-of-bounds read and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16533)

  - The cdc_parse_cdc_header() function in     'drivers/usb/core/message.c' in the Linux kernel,     before 4.13.6, allows local users to cause a denial of     service (out-of-bounds read and system crash) or     possibly have unspecified other impact via a crafted     USB device. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2017-16534)

  - The usb_get_bos_descriptor function in     drivers/usb/core/config.c in the Linux kernel can allow     a local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB     device.(CVE-2017-16535)

  - The cx231xx_usb_probe function in     drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux     kernel through 4.13.11 allows local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16536)

  - The imon_probe function in drivers/media/rc/imon.c in     the Linux kernel through 4.13.11 allows local users to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16537)

  - The drivers/media/usb/dvb-usb-v2/lmedm04.c in the Linux     kernel, through 4.13.11, allows local users to cause a     denial of service (general protection fault and system     crash) or possibly have unspecified other impact via a     crafted USB device, related to a missing warm-start     check and incorrect attach timing     (dm04_lme2510_frontend_attach versus     dm04_lme2510_tuner).(CVE-2017-16538)

  - The parse_hid_report_descriptor function in     drivers/input/tablet/gtco.c in the Linux kernel before     4.13.11 allows local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB     device.(CVE-2017-16643)

  - The hdpvr_probe function in     drivers/media/usb/hdpvr/hdpvr-core.c in the Linux     kernel through 4.13.11 allows local users to cause a     denial of service (improper error handling and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16644)

  - The ims_pcu_get_cdc_union_desc function in     drivers/input/misc/ims-pcu.c in the Linux kernel,     through 4.13.11, allows local users to cause a denial     of service (ims_pcu_parse_cdc_data out-of-bounds read     and system crash) or possibly have unspecified other     impact via a crafted USB device.(CVE-2017-16645)

  - The usbnet_generic_cdc_bind function in     drivers/net/usb/cdc_ether.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (divide-by-zero error and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16649)

  - The qmi_wwan_bind function in     drivers/net/usb/qmi_wwan.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (divide-by-zero error and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16650)

  - The Linux kernel is vulerable to a use-after-free flaw     when Transformation User configuration     interface(CONFIG_XFRM_USER) compile-time configuration     were enabled. This vulnerability occurs while closing a     xfrm netlink socket in xfrm_dump_policy_done. A     user/process could abuse this flaw to potentially     escalate their privileges on a system.(CVE-2017-16939)

  - The net/netfilter/nfnetlink_cthelper.c function in the     Linux kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for new, get, and del     operations. This allows local users to bypass intended     access restrictions because the nfnl_cthelper_list data     structure is shared across all net     namespaces.(CVE-2017-17448)

  - The __netlink_deliver_tap_skb function in     net/netlink/af_netlink.c in the Linux kernel, through     4.14.4, does not restrict observations of Netlink     messages to a single net namespace, when CONFIG_NLMON     is enabled. This allows local users to obtain sensitive     information by leveraging the CAP_NET_ADMIN capability     to sniff an nlmon interface for all Netlink activity on     the system.(CVE-2017-17449)

  - net/netfilter/xt_osf.c in the Linux kernel through     4.14.4 does not require the CAP_NET_ADMIN capability     for add_callback and remove_callback operations. This     allows local users to bypass intended access     restrictions because the xt_osf_fingers data structure     is shared across all network     namespaces.(CVE-2017-17450)

  - The usb_destroy_configuration() function, in     'drivers/usb/core/config.c' in the USB core subsystem,     in the Linux kernel through 4.14.5 does not consider     the maximum number of configurations and interfaces     before attempting to release resources. This allows     local users to cause a denial of service, due to     out-of-bounds write access, or possibly have     unspecified other impact via a crafted USB device. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-17558)

  - The Salsa20 encryption algorithm in the Linux kernel,     before 4.14.8, does not correctly handle zero-length     inputs. This allows a local attacker the ability to use     the AF_ALG-based skcipher interface to cause a denial     of service (uninitialized-memory free and kernel crash)     or have an unspecified other impact by executing a     crafted sequence of system calls that use the     blkcipher_walk API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 are     vulnerable.(CVE-2017-17805)

  - The HMAC implementation (crypto/hmac.c) in the Linux     kernel, before 4.14.8, does not validate that the     underlying cryptographic hash algorithm is unkeyed.
    This allows a local attacker, able to use the     AF_ALG-based hash interface     (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash     algorithm (CONFIG_CRYPTO_SHA3), to cause a kernel stack     buffer overflow by executing a crafted sequence of     system calls that encounter a missing SHA-3     initialization.(CVE-2017-17806)

  - The KEYS subsystem in the Linux kernel omitted an     access-control check when writing a key to the current     task's default keyring, allowing a local user to bypass     security checks to the keyring. This compromises the     validity of the keyring for those who rely on     it.(CVE-2017-17807)

  - A flaw was found in the Linux kernel's implementation     of i8042 serial ports. An attacker could cause a kernel     panic if they are able to add and remove devices as the     module is loaded.(CVE-2017-18079)

  - The Linux kernel, before version 4.14.3, is vulnerable     to a denial of service in     drivers/md/dm.c:dm_get_from_kobject() which can be     caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM     devices. Only privileged local users (with     CAP_SYS_ADMIN capability) can directly perform the     ioctl operations for dm device creation and removal and     this would typically be outside the direct control of     the unprivileged attacker.(CVE-2017-18203)

  - The madvise_willneed function in the Linux kernel     allows local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping.(CVE-2017-18208)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: out of bounds read in drivers/media/usb/dvb-usb/technisat-usb2.c (CVE-2019-15505)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - block/scsi_ioctl.c in the Linux kernel through 3.8 does not properly consider the SCSI device class during     authorization of SCSI commands, which allows local users to bypass intended access restrictions via an     SG_IO ioctl call that leverages overlapping opcodes. (CVE-2012-4542)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
