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)

Updated kernel-rt packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise MRG 2.3.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Security fixes :

* It was found that the kernel-rt update RHBA-2012:0044 introduced an integer conversion issue in the Linux kernel's Performance Events implementation. 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.
(CVE-2013-2634, CVE-2013-2635, CVE-2013-3076, CVE-2013-3222, CVE-2013-3224, CVE-2013-3225, CVE-2013-3231, Low)
