The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-4710 advisory.

    - fork: record start_time late (David Herrmann)  [Orabug: 29850581]  {CVE-2019-6133}
    - x86/retpoline/ia32entry: Convert to non-speculative calls (Ankur Arora)  [Orabug: 29909295]     {CVE-2017-5715}
    - tun: call dev_get_valid_name() before register_netdevice() (Cong Wang)  [Orabug: 29925555]     {CVE-2018-7191}

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.

The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic.

CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection.

CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data.
Further, it would consume additional resources such as CPU and NIC processing power.

CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bnc#1136424)

CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel, there was an unchecked kstrdup of fwstr, which might have allowed an attacker to cause a denial of service (NULL pointer dereference and system crash).
(bnc#1136586)

CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may have been possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bnc#1120843)

CVE-2019-11487: The Linux kernel allowed page reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM existed. It could have occured with FUSE requests. (bnc#1133190)

CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might have allowed local users to obtain sensitive information by reading uninitialized data in the filesystem. (bnc#1135281)

CVE-2018-7191: In the tun subsystem in the Linux kernel, dev_get_valid_name was not called before register_netdevice. This allowed local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. (bnc#1135603)

CVE-2019-11085: Insufficient input validation in Kernel Mode Driver in i915 Graphics for Linux may have allowed an authenticated user to potentially enable escalation of privilege via local access.
(bnc#1135278)

CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel There was a race condition leading to a use-after-free, related to net namespace cleanup. (bnc#1134537)

CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a '\0' character. (bnc#1134848)

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel had multiple race conditions. (bnc#1133188)

The update package also includes non-security fixes. See advisory for details.

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