"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-2007-6716
    Joe Jin reported a local denial of service vulnerability
    that allows system users to trigger an oops due to an
    improperly initialized data structure.

  - CVE-2008-1514
    Jan Kratochvil reported a local denial of service
    vulnerability in the ptrace interface for the s390
    architecture. Local users can trigger an invalid pointer
    dereference, leading to a system panic.

  - CVE-2008-3276
    Eugene Teo reported an integer overflow in the DCCP
    subsystem that may allow remote attackers to cause a
    denial of service in the form of a kernel panic.

  - CVE-2008-3525
    Eugene Teo reported a lack of capability checks in the
    kernel driver for Granch SBNI12 leased line adapters
    (sbni), allowing local users to perform privileged
    operations.

  - CVE-2008-3833
    The S_ISUID/S_ISGID bits were not being cleared during
    an inode splice, which, under certain conditions, can be
    exploited by local users to obtain the privileges of a
    group for which they are not a member. Mark Fasheh
    reported this issue.

  - CVE-2008-4210
    David Watson reported an issue in the open()/creat()
    system calls which, under certain conditions, can be
    exploited by local users to obtain the privileges of a
    group for which they are not a member.

  - CVE-2008-4302
    A coding error in the splice subsystem allows local
    users to attempt to unlock a page structure that has not
    been locked, resulting in a system crash."
