The SUSE Linux Enterprise 11 Service Pack 3 kernel has been updated to 3.0.82 and to fix various bugs and security issues.

The following security issues have been fixed :

  - The chase_port function in drivers/usb/serial/io_ti.c in     the Linux kernel allowed local users to cause a denial     of service (NULL pointer dereference and system crash)     via an attempted /dev/ttyUSB read or write operation on     a disconnected Edgeport USB serial converter.
    (CVE-2013-1774)

  - Timing side channel on attacks were possible on     /dev/ptmx that could allow local attackers to predict     keypresses like e.g. passwords. This has been fixed     again by updating accessed/modified time on the pty     devices in resolution of 8 seconds, so that idle time     detection can still work. (CVE-2013-0160)

  - The vcc_recvmsg function in net/atm/common.c in the     Linux kernel did not initialize a certain length     variable, which allowed local users to obtain sensitive     information from kernel stack memory via a crafted     recvmsg or recvfrom system call. (CVE-2013-3222)

  - The ax25_recvmsg function in net/ax25/af_ax25.c in the     Linux kernel did not initialize a certain data     structure, which allowed local users to obtain sensitive     information from kernel stack memory via a crafted     recvmsg or recvfrom system call. (CVE-2013-3223)

  - The bt_sock_recvmsg function in     net/bluetooth/af_bluetooth.c in the Linux kernel did not     properly initialize a certain length variable, which     allowed local users to obtain sensitive information from     kernel stack memory via a crafted recvmsg or recvfrom     system call. (CVE-2013-3224)

  - The rfcomm_sock_recvmsg function in     net/bluetooth/rfcomm/sock.c in the Linux kernel did not     initialize a certain length variable, which allowed     local users to obtain sensitive information from kernel     stack memory via a crafted recvmsg or recvfrom system     call. (CVE-2013-3225)

  - The caif_seqpkt_recvmsg function in     net/caif/caif_socket.c in the Linux kernel did not     initialize a certain length variable, which allowed     local users to obtain sensitive information from kernel     stack memory via a crafted recvmsg or recvfrom system     call. (CVE-2013-3227)

  - The irda_recvmsg_dgram function in net/irda/af_irda.c in     the Linux kernel did not initialize a certain length     variable, which allowed local users to obtain sensitive     information from kernel stack memory via a crafted     recvmsg or recvfrom system call. (CVE-2013-3228)

  - The iucv_sock_recvmsg function in net/iucv/af_iucv.c in     the Linux kernel did not initialize a certain length     variable, which allowed local users to obtain sensitive     information from kernel stack memory via a crafted     recvmsg or recvfrom system call. (CVE-2013-3229)

  - The llc_ui_recvmsg function in net/llc/af_llc.c in the     Linux kernel did not initialize a certain length     variable, which allowed local users to obtain sensitive     information from kernel stack memory via a crafted     recvmsg or recvfrom system call. (CVE-2013-3231)

  - The nr_recvmsg function in net/netrom/af_netrom.c in the     Linux kernel did not initialize a certain data     structure, which allowed local users to obtain sensitive     information from kernel stack memory via a crafted     recvmsg or recvfrom system call. (CVE-2013-3232)

  - The rose_recvmsg function in net/rose/af_rose.c in the     Linux kernel did not initialize a certain data     structure, which allowed local users to obtain sensitive     information from kernel stack memory via a crafted     recvmsg or recvfrom system call. (CVE-2013-3234)

  - net/tipc/socket.c in the Linux kernel did not initialize     a certain data structure and a certain length variable,     which allowed local users to obtain sensitive     information from kernel stack memory via a crafted     recvmsg or recvfrom system call. (CVE-2013-3235)

  - The crypto API in the Linux kernel did not initialize     certain length variables, which allowed local users to     obtain sensitive information from kernel stack memory     via a crafted recvmsg or recvfrom system call, related     to the hash_recvmsg function in crypto/algif_hash.c and     the skcipher_recvmsg function in     crypto/algif_skcipher.c. (CVE-2013-3076)

  - The scm_set_cred function in include/net/scm.h in the     Linux kernel used incorrect uid and gid values during     credentials passing, which allowed local users to gain     privileges via a crafted application. (CVE-2013-1979)

This led to a user-supplied index into the perf_swevent_enabled array not being validated properly, resulting in out-of-bounds kernel memory access. A local, unprivileged user could use this flaw to escalate their privileges. (CVE-2013-2094, Important)

A public exploit for CVE-2013-2094 that affects Red Hat Enterprise MRG 2 is available. Refer to Red Hat Knowledge Solution 373743, linked to in the References, for further information and mitigation instructions for users who are unable to immediately apply this update.

* An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the Intel i915 driver in the Linux kernel handled the allocation of the buffer used for relocation copies. A local user with console access could use this flaw to cause a denial of service or escalate their privileges. (CVE-2013-0913, Important)

* It was found that the Linux kernel used effective user and group IDs instead of real ones when passing messages with SCM_CREDENTIALS ancillary data. A local, unprivileged user could leverage this flaw with a set user ID (setuid) application, allowing them to escalate their privileges. (CVE-2013-1979, Important)

* A race condition in install_user_keyrings(), leading to a NULL pointer dereference, was found in the key management facility. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2013-1792, Moderate)

* A NULL pointer dereference flaw was found in the Linux kernel's XFS file system implementation. A local user who is able to mount an XFS file system could use this flaw to cause a denial of service.
(CVE-2013-1819, Moderate)

* An information leak was found in the Linux kernel's POSIX signals implementation. A local, unprivileged user could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature.
(CVE-2013-0914, Low)

* A use-after-free flaw was found in the tmpfs implementation. A local user able to mount and unmount a tmpfs file system could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1767, Low)

* A NULL pointer dereference flaw was found in the Linux kernel's USB Inside Out Edgeport Serial Driver implementation. A local user with physical access to a system and with access to a USB device's tty file could use this flaw to cause a denial of service. (CVE-2013-1774, Low)

* A format string flaw was found in the ext3_msg() function in the Linux kernel's ext3 file system implementation. A local user who is able to mount an ext3 file system could use this flaw to cause a denial of service or, potentially, escalate their privileges.
(CVE-2013-1848, Low)

* A heap-based buffer overflow flaw was found in the Linux kernel's cdc-wdm driver, used for USB CDC WCM device management. An attacker with physical access to a system could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1860, Low)

* A heap-based buffer overflow in the way the tg3 Ethernet driver parsed the vital product data (VPD) of devices could allow an attacker with physical access to a system to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1929, Low)

* Information leaks in the Linux kernel's cryptographic API could allow a local user who has the CAP_NET_ADMIN capability to leak kernel stack memory to user-space. (CVE-2013-2546, CVE-2013-2547, CVE-2013-2548, Low)

* Information leaks in the Linux kernel could allow a local, unprivileged user to leak kernel stack memory to user-space.

For more information on this set of information leaks, check out https://www.suse.com/support/kb/doc/?id=7023736

The following security bugs were fixed: CVE-2019-9213: The expand_downwards function in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166).

CVE-2013-0216: The Xen netback functionality allowed guest OS users to cause a denial of service (loop) by triggering ring pointer corruption (bnc#800280).

CVE-2013-0231: The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen allowed guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages. (bnc#801178).

CVE-2012-3430: The rds_recvmsg function in net/rds/recv.c did not initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a recvfrom or recvmsg system call on an RDS socket (bnc#773383).

CVE-2012-3412: The sfc (aka Solarflare Solarstorm) driver allowed remote attackers to cause a denial of service (DMA descriptor consumption and network-controller outage) via crafted TCP packets that trigger a small MSS value (bnc#774523).

CVE-2013-0160: The kernel allowed local users to obtain sensitive information about keystroke timing by using the inotify API on the /dev/ptmx device (bnc#797175).

CVE-2013-1979: The scm_set_cred function in include/net/scm.h uses incorrect uid and gid values during credentials passing, which allowed local users to gain privileges via a crafted application (bnc#816708).

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