The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:0429 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux     operating system.

    This update fixes the following security issues:

    * A missing boundary check was found in the dvb_ca_ioctl() function in the     Linux kernel's av7110 module. On systems that use old DVB cards that     require the av7110 module, a local, unprivileged user could use this flaw     to cause a denial of service or escalate their privileges. (CVE-2011-0521,     Important)

    * An inconsistency was found in the interaction between the Linux kernel's     method for allocating NFSv4 (Network File System version 4) ACL data and     the method by which it was freed. This inconsistency led to a kernel panic     which could be triggered by a local, unprivileged user with files owned by     said user on an NFSv4 share. (CVE-2011-1090, Moderate)

    * A NULL pointer dereference flaw was found in the Generic Receive Offload     (GRO) functionality in the Linux kernel's networking implementation. If     both GRO and promiscuous mode were enabled on an interface in a virtual LAN     (VLAN), it could result in a denial of service when a malformed VLAN frame     is received on that interface. (CVE-2011-1478, Moderate)

    * A missing security check in the Linux kernel's implementation of the     install_special_mapping() function could allow a local, unprivileged user     to bypass the mmap_min_addr protection mechanism. (CVE-2010-4346, Low)

    * An information leak was found in the Linux kernel's task_show_regs()     implementation. On IBM S/390 systems, a local, unprivileged user could use     this flaw to read /proc/[PID]/status files, allowing them to discover the     CPU register values of processes. (CVE-2011-0710, Low)

    * A missing validation check was found in the Linux kernel's     mac_partition() implementation, used for supporting file systems created     on Mac OS operating systems. A local attacker could use this flaw to cause     a denial of service by mounting a disk that contains specially-crafted     partitions. (CVE-2011-1010, Low)

    Red Hat would like to thank Ryan Sweat for reporting CVE-2011-1478; Tavis     Ormandy for reporting CVE-2010-4346; and Timo Warns for reporting     CVE-2011-1010.

    This update also fixes several bugs. Documentation for these bug fixes will     be available shortly from the Technical Notes document linked to in the     References section.

    Users should upgrade to these updated packages, which contain backported     patches to correct these issues, and fix the bugs noted in the Technical     Notes. The system must be rebooted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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