The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0010 advisory.

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

    This update fixes the following security issues:

    * A malicious CIFS (Common Internet File System) server could send a     specially-crafted response to a directory read request that would result in     a denial of service or privilege escalation on a system that has a CIFS     share mounted. (CVE-2011-3191, Important)

    * The way fragmented IPv6 UDP datagrams over the bridge with UDP     Fragmentation Offload (UFO) functionality on were handled could allow a     remote attacker to cause a denial of service. (CVE-2011-4326, Important)

    * GRO (Generic Receive Offload) fields could be left in an inconsistent     state. An attacker on the local network could use this flaw to cause a     denial of service. GRO is enabled by default in all network drivers that     support it. (CVE-2011-2723, Moderate)

    * IPv4 and IPv6 protocol sequence number and fragment ID generation could     allow a man-in-the-middle attacker to inject packets and possibly hijack     connections. Protocol sequence numbers and fragment IDs are now more     random. (CVE-2011-3188, Moderate)

    * A flaw in the FUSE (Filesystem in Userspace) implementation could allow     a local user in the fuse group who has access to mount a FUSE file system     to cause a denial of service. (CVE-2011-3353, Moderate)

    * A flaw in the b43 driver. If a system had an active wireless interface     that uses the b43 driver, an attacker able to send a specially-crafted     frame to that interface could cause a denial of service. (CVE-2011-3359,     Moderate)

    * A flaw in the way CIFS shares with DFS referrals at their root were     handled could allow an attacker on the local network, who is able to deploy     a malicious CIFS server, to create a CIFS network share that, when mounted,     would cause the client system to crash. (CVE-2011-3363, Moderate)

    * A flaw in the m_stop() implementation could allow a local, unprivileged     user to trigger a denial of service. (CVE-2011-3637, Moderate)

    * Flaws in ghash_update() and ghash_final() could allow a local,     unprivileged user to cause a denial of service. (CVE-2011-4081, Moderate)

    * A flaw in the key management facility could allow a local, unprivileged     user to cause a denial of service via the keyctl utility. (CVE-2011-4110,     Moderate)

    * A flaw in the Journaling Block Device (JBD) could allow a local attacker     to crash the system by mounting a specially-crafted ext3 or ext4 disk.
    (CVE-2011-4132, Moderate)

    * A flaw in the way memory containing security-related data was handled in     tpm_read() could allow a local, unprivileged user to read the results of a     previously run TPM command. (CVE-2011-1162, Low)

    * I/O statistics from the taskstats subsystem could be read without any     restrictions, which could allow a local, unprivileged user to gather     confidential information, such as the length of a password used in a     process. (CVE-2011-2494, Low)

    * Flaws in tpacket_rcv() and packet_recvmsg() could allow a local,     unprivileged user to leak information to user-space. (CVE-2011-2898, Low)

    Red Hat would like to thank Darren Lavender for reporting CVE-2011-3191;
    Brent Meshier for reporting CVE-2011-2723; Dan Kaminsky for reporting     CVE-2011-3188; Yogesh Sharma for reporting CVE-2011-3363; Nick Bowler for     reporting CVE-2011-4081; Peter Huewe for reporting CVE-2011-1162; and     Vasiliy Kulikov of Openwall for reporting CVE-2011-2494.

    This update also fixes the following bugs:

    * Previously, a mismatch in the build-id of the kernel-rt and the one in     the related debuginfo package caused failures in SystemTap and perf.
    (BZ#768413)

    * IBM x3650m3 systems were not able to boot the MRG Realtime kernel because     they require a pmcraid driver that was not available. The pmcraid driver is     included in this update. (BZ#753992)

    Users should upgrade to these updated packages, which correct these issues.
    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.

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

This update fixes the following security issues :

  - A buffer overflow flaw was found in the way the Linux     kernel's XFS file system implementation handled links     with overly long path names. A local, unprivileged user     could use this flaw to cause a denial of service or     escalate their privileges by mounting a specially     crafted disk. (CVE-2011-4077, Important)

  - The fix for CVE-2011-2482 provided by a previous update     introduced a regression: on systems that do not have     Security-Enhanced Linux (SELinux) in Enforcing mode, a     socket lock race could occur between sctp_rcv() and     sctp_accept(). A remote attacker could use this flaw to     cause a denial of service. By default, SELinux runs in     Enforcing mode on Scientific Linux 5. (CVE-2011-4348,     Important)

  - The proc file system could allow a local, unprivileged     user to obtain sensitive information or possibly cause     integrity issues. (CVE-2011-1020, Moderate)

  - A missing validation flaw was found in the Linux     kernel's m_stop() implementation. A local, unprivileged     user could use this flaw to trigger a denial of service.
    (CVE-2011-3637, Moderate)

  - A flaw was found in the Linux kernel's Journaling Block     Device (JBD). A local attacker could use this flaw to     crash the system by mounting a specially crafted ext3 or     ext4 disk. (CVE-2011-4132, Moderate)

  - A flaw was found in the Linux kernel's     encode_share_access() implementation. A local,     unprivileged user could use this flaw to trigger a     denial of service by creating a regular file on an NFSv4     (Network File System version 4) file system via mknod().
    (CVE-2011-4324, Moderate)

  - A flaw was found in the Linux kernel's NFS     implementation. A local, unprivileged user could use     this flaw to cause a denial of service. (CVE-2011-4325,     Moderate)

  - A missing boundary check was found in the Linux kernel's     HFS file system implementation. A local attacker could     use this flaw to cause a denial of service or escalate     their privileges by mounting a specially crafted disk.
    (CVE-2011-4330, Moderate)

This update also fixes several bugs and adds one enhancement.

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