This update fixes the following security issues :

  - IPv6 fragment identification value generation could
    allow a remote attacker to disrupt a target system's
    networking, preventing legitimate users from accessing
    its services. (CVE-2011-2699, Important)

  - A signedness issue was found in the Linux kernel's CIFS
    (Common Internet File System) implementation. A
    malicious CIFS 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)

  - A flaw was found in the way the Linux kernel handled
    fragmented IPv6 UDP datagrams over the bridge with UDP
    Fragmentation Offload (UFO) functionality on. A remote
    attacker could use this flaw to cause a denial of
    service. (CVE-2011-4326, Important)

  - The way IPv4 and IPv6 protocol sequence numbers and
    fragment IDs were generated 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 buffer overflow flaw was found in the Linux kernel's
    FUSE (Filesystem in Userspace) implementation. A local
    user in the fuse group who has access to mount a FUSE
    file system could use this flaw to cause a denial of
    service. (CVE-2011-3353, Moderate)

  - A flaw was found in the b43 driver in the Linux kernel.
    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 was found in the way CIFS shares with DFS
    referrals at their root were handled. An attacker on the
    local network who is able to deploy a malicious CIFS
    server could create a CIFS network share that, when
    mounted, would cause the client system to crash.
    (CVE-2011-3363, Moderate)

  - A flaw was found in the way the Linux kernel handled
    VLAN 0 frames with the priority tag set. When using
    certain network drivers, an attacker on the local
    network could use this flaw to cause a denial of
    service. (CVE-2011-3593, 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)

  - A heap overflow flaw was found in the Linux kernel's EFI
    GUID Partition Table (GPT) implementation. A local
    attacker could use this flaw to cause a denial of
    service by mounting a disk that contains specially
    crafted partition tables. (CVE-2011-1577, Low)

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

  - It was found that the perf tool, a part of the Linux
    kernel's Performance Events implementation, could load
    its configuration file from the current working
    directory. If a local user with access to the perf tool
    were tricked into running perf in a directory that
    contains a specially crafted configuration file, it
    could cause perf to overwrite arbitrary files and
    directories accessible to that user. (CVE-2011-2905,
    Low)
