"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service or privilege escalation. The Common
Vulnerabilities and Exposures project identifies the following
problems :

  - CVE-2009-0029
    Christian Borntraeger discovered an issue effecting the
    alpha, mips, powerpc, s390 and sparc64 architectures
    that allows local users to cause a denial of service or
    potentially gain elevated privileges.

  - CVE-2009-0031
    Vegard Nossum discovered a memory leak in the keyctl
    subsystem that allows local users to cause a denial of
    service by consuming all of kernel memory.

  - CVE-2009-0065
    Wei Yongjun discovered a memory overflow in the SCTP
    implementation that can be triggered by remote users.

  - CVE-2009-0269
    Duane Griffin provided a fix for an issue in the
    eCryptfs subsystem which allows local users to cause a
    denial of service (fault or memory corruption).

  - CVE-2009-0322
    Pavel Roskin provided a fix for an issue in the dell_rbu
    driver that allows a local user to cause a denial of
    service (oops) by reading 0 bytes from a sysfs entry.

  - CVE-2009-0676
    Clement LECIGNE discovered a bug in the sock_getsockopt
    function that may result in leaking sensitive kernel
    memory.

  - CVE-2009-0675
    Roel Kluin discovered inverted logic in the skfddi
    driver that permits local, unprivileged users to reset
    the driver statistics.

  - CVE-2009-0745
    Peter Kerwien discovered an issue in the ext4 filesystem
    that allows local users to cause a denial of service
    (kernel oops) during a resize operation.

  - CVE-2009-0746
    Sami Liedes reported an issue in the ext4 filesystem
    that allows local users to cause a denial of service
    (kernel oops) when accessing a specially crafted corrupt
    filesystem.

  - CVE-2009-0747
    David Maciejak reported an issue in the ext4 filesystem
    that allows local users to cause a denial of service
    (kernel oops) when mounting a specially crafted corrupt
    filesystem.

  - CVE-2009-0748
    David Maciejak reported an additional issue in the ext4
    filesystem that allows local users to cause a denial of
    service (kernel oops) when mounting a specially crafted
    corrupt filesystem."
