New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThis Linux kernel update fixes various security issues and bugs in the SUSE Linux Enterprise 10 SP4 kernel.
The following security issues have been fixed :
CVE-2011-2494: kernel/taskstats.c in the Linux kernel allowed local users to obtain sensitive I/O statistics by sending taskstats commands to a netlink socket, as demonstrated by discovering the length of another users password (a side channel attack).
CVE-2012-2744: net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux kernel, when the nf_conntrack_ipv6 module is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets.
CVE-2012-3510: Use-after-free vulnerability in the xacct_add_tsk function in kernel/tsacct.c in the Linux kernel allowed local users to obtain potentially sensitive information from kernel memory or cause a denial of service (system crash) via a taskstats TASKSTATS_CMD_ATTR_PID command.
CVE-2011-4110: The user_update function in security/keys/user_defined.c in the Linux kernel 2.6 allowed local users to cause a denial of service (NULL pointer dereference and kernel oops) via vectors related to a user-defined key and updating a negative key into a fully instantiated key.
CVE-2011-1044: The ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel did not initialize a certain response buffer, which allowed local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially filled, a different vulnerability than CVE-2010-4649.
CVE-2012-3400: Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel allowed remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.
CVE-2012-2136: The sock_alloc_send_pskb function in net/core/sock.c in the Linux kernel did not properly validate a certain length value, which allowed local users to cause a denial of service (heap-based buffer overflow and system crash) or possibly gain privileges by leveraging access to a TUN/TAP device.
CVE-2012-2663: A small denial of service leak in dropping syn+fin messages was fixed.

- sunrpc/cache: Another fix for race problem with sunrpc cache deferal (bnc#767766).
- knfsd: nfsd: make all exp_finding functions return
-errnos on err (bnc#767766).
- Fix kabi breakage in previous nfsd patch series (bnc#767766).

- nfs: fix reference counting for NFSv4 callback thread (bnc#767504).
- nfs: flush signals before taking down callback thread (bnc#767504).
- nfsv4: Ensure nfs_callback_down() calls svc_destroy() (bnc#767504).
- SCSI/ch: Check NULL for kmalloc() return (bnc#783058).
drivers/scsi/aic94xx/aic94xx_init.c: correct the size argument to kmalloc (bnc#783058).
block: fail SCSI passthrough ioctls on partition devices (bnc#738400).
