The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-1064 advisory.

    - [kernel] Prevent keyctl new_session from causing a panic (David Howells) [833433 827424] {CVE-2012-2745}
    - [net] ipv6/netfilter: fix null pointer dereference in nf_ct_frag6_reasm() (Petr Matousek) [833410     833412] {CVE-2012-2744}

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This 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.

The following non-security issues have been fixed :
