    Package        : kernel-patch-2.4.18-powerpc, kernel-image-2.4.18-1-alpha
    Vulnerability  : mising boundary check
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : CAN-2003-0985
    Paul Starzetz discovered a flaw in bounds checking in mremap() in the
    Linux kernel (present in version 2.4.x and 2.6.x) which may allow a
    local attacker to gain root privileges.  Version 2.2 is not affected
    by this bug.
    For the stable distribution (woody) this problem has been fixed in
    version 2.4.18-1woody3 for the powerpc architecture.
    For the unstable distribution (sid) this problem will be fixed soon
    with newly uploaded packages.
    We recommend that you upgrade your kernel packages.  This problem has
    been fixed in the upstream version 2.4.24 as well.
