    linux-source-2.6.15 vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 6.06 LTS
    Multiple flaws fixed in the Linux kernel.
    Software Description:
    - linux-source-2.6.15: Linux kernel
    Dan Rosenberg discovered multiple flaws in the X.25 facilities parsing. If
    a system was using X.25, a remote attacker could exploit this to crash the
    system, leading to a denial of service. (CVE-2010-4164)
    Vegard Nossum discovered that memory garbage collection was not handled
    correctly for active sockets. A local attacker could exploit this to
    allocate all available kernel memory, leading to a denial of service.
    Nelson Elhage discovered that the kernel did not correctly handle process
    cleanup after triggering a recoverable kernel bug. If a local attacker were
    able to trigger certain kinds of kernel bugs, they could create a specially
    crafted process to gain root privileges. (CVE-2010-4258)
    Nelson Elhage discovered that Econet did not correctly handle AUN packets
    over UDP. A local attacker could send specially crafted traffic to crash
    the system, leading to a denial of service. (CVE-2010-4342)
    Dan Rosenberg discovered that the OSS subsystem did not handle name
    termination correctly. A local attacker could exploit this crash the system
    or gain root privileges. (CVE-2010-4527)
    Dan Rosenberg discovered that IRDA did not correctly check the size of
    buffers. On non-x86 systems, a local attacker could exploit this to read
    kernel heap memory, leading to a loss of privacy. (CVE-2010-4529)
    Dan Carpenter discovered that the TTPCI DVB driver did not check certain
    values during an ioctl. If the dvb-ttpci module was loaded, a local
    attacker could exploit this to crash the system, leading to a denial of
    service, or possibly gain root privileges. (CVE-2011-0521)
    Jens Kuehnel discovered that the InfiniBand driver contained a race
    condition. On systems using InfiniBand, a local attacker could send
    specially crafted requests to crash the system, leading to a denial of
    service. (CVE-2011-0695)
    Timo Warns discovered that the LDM disk partition handling code did not
    correctly handle certain values. By inserting a specially crafted disk
    device, a local attacker could exploit this to gain root privileges.
