"This kernel update for the SUSE Linux Enterprise 10 SP3 kernel fixes
several security issues and bugs.

The following security issues were fixed :

  - A local attacker could use a Oops (kernel crash) caused
    by other flaws to write a 0 byte to a attacker
    controlled address in the kernel. This could lead to
    privilege escalation together with other issues.
    (CVE-2010-4258)

  - The backend driver in Xen 3.x allows guest OS users to
    cause a denial of service via a kernel thread leak,
    which prevents the device and guest OS from being shut
    down or create a zombie domain, causes a hang in
    zenwatch, or prevents unspecified xm commands from
    working properly, related to (1) netback, (2) blkback,
    or (3) blktap. (CVE-2010-3699)

  - The econet_sendmsg function in net/econet/af_econet.c in
    the Linux kernel, when an econet address is configured,
    allowed local users to cause a denial of service (NULL
    pointer dereference and OOPS) via a sendmsg call that
    specifies a NULL value for the remote address field.
    (CVE-2010-3849)

  - Stack-based buffer overflow in the econet_sendmsg
    function in net/econet/af_econet.c in the Linux kernel
    when an econet address is configured, allowed local
    users to gain privileges by providing a large number of
    iovec structures. (CVE-2010-3848)

  - The ec_dev_ioctl function in net/econet/af_econet.c in
    the Linux kernel did not require the CAP_NET_ADMIN
    capability, which allowed local users to bypass intended
    access restrictions and configure econet addresses via
    an SIOCSIFADDR ioctl call. (CVE-2010-3850)

  - A overflow in sendto() and recvfrom() routines was fixed
    that could be used by local attackers to potentially
    crash the kernel using some socket families like L2TP.
    (CVE-2010-4160)"
