The SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.45 and fixes various bugs and security issues.

The following security issues have been fixed :

  - Timo Warns reported an issue in the Linux implementation     for GUID partitions. Users with physical access could     gain access to sensitive kernel memory by adding a     storage device with a specially crafted corrupted     invalid partition table. (CVE-2011-1776)

  - The second part of this fix was not yet applied to our     kernel: arch/x86/kvm/x86.c in the Linux kernel before     2.6.36.2 does not initialize certain structure members,     which allows local users to obtain potentially sensitive     information from kernel stack memory via read operations     on the /dev/kvm device. (CVE-2010-3881)

  - The /proc/PID/io interface could be used by local     attackers to gain information on other processes like     number of password characters typed or similar.
    (CVE-2011-2495)

  - A small buffer overflow in the radio driver si4713-i2c     was fixed that could potentially used by local attackers     to crash the kernel or potentially execute code.
    (CVE-2011-2700)

  - A kernel information leak in the comedi driver from     kernel to userspace was fixed. (CVE-2011-2909)

  - In the perf framework software event overflows could     deadlock or delete an uninitialized timer.
    (CVE-2011-2918)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2011-1020     Kees Cook discovered an issue in the /proc filesystem     that allows local users to gain access to sensitive     process information after execution of a setuid binary.

  - CVE-2011-1576     Ryan Sweat discovered an issue in the VLAN     implementation. Local users may be able to cause a     kernel memory leak, resulting in a denial of service.

  - CVE-2011-2484     Vasiliy Kulikov of Openwall discovered that the number     of exit handlers that a process can register is not     capped, resulting in local denial of service through     resource exhaustion (CPU time and memory).

  - CVE-2011-2491     Vasily Averin discovered an issue with the NFS locking     implementation. A malicious NFS server can cause a     client to hang indefinitely in an unlock call.

  - CVE-2011-2492     Marek Kroemeke and Filip Palian discovered that     uninitialized struct elements in the Bluetooth subsystem     could lead to a leak of sensitive kernel memory through     leaked stack memory.

  - CVE-2011-2495     Vasiliy Kulikov of Openwall discovered that the io file     of a process' proc directory was world-readable,     resulting in local information disclosure of information     such as password lengths.

  - CVE-2011-2496     Robert Swiecki discovered that mremap() could be abused     for local denial of service by triggering a BUG_ON     assert.

  - CVE-2011-2497     Dan Rosenberg discovered an integer underflow in the     Bluetooth subsystem, which could lead to denial of     service or privilege escalation.

  - CVE-2011-2517     It was discovered that the netlink-based wireless     configuration interface performed insufficient length     validation when parsing SSIDs, resulting in buffer     overflows. Local users with the CAP_NET_ADMIN capability     can cause a denial of service.

  - CVE-2011-2525     Ben Pfaff reported an issue in the network scheduling     code. A local user could cause a denial of service (NULL     pointer dereference) by sending a specially crafted     netlink message.

  - CVE-2011-2700     Mauro Carvalho Chehab of Red Hat reported a buffer     overflow issue in the driver for the Si4713 FM Radio     Transmitter driver used by N900 devices. Local users     could exploit this issue to cause a denial of service or     potentially gain elevated privileges.

  - CVE-2011-2723     Brent Meshier reported an issue in the GRO (generic     receive offload) implementation. This can be exploited     by remote users to create a denial of service (system     crash) in certain network device configurations.

  - CVE-2011-2905     Christian Ohm discovered that the 'perf' analysis tool     searches for its config files in the current working     directory. This could lead to denial of service or     potential privilege escalation if a user with elevated     privileges is tricked into running 'perf' in a directory     under the control of the attacker.

  - CVE-2011-2909     Vasiliy Kulikov of Openwall discovered that a     programming error in the Comedi driver could lead to the     information disclosure through leaked stack memory.

  - CVE-2011-2918     Vince Weaver discovered that incorrect handling of     software event overflows in the 'perf' analysis tool     could lead to local denial of service.

  - CVE-2011-2928     Timo Warns discovered that insufficient validation of Be     filesystem images could lead to local denial of service     if a malformed filesystem image is mounted.

  - CVE-2011-3188     Dan Kaminsky reported a weakness of the sequence number     generation in the TCP protocol implementation. This can     be used by remote attackers to inject packets into an     active session.

  - CVE-2011-3191     Darren Lavender reported an issue in the Common Internet     File System (CIFS). A malicious file server could cause     memory corruption leading to a denial of service.
