    Package        : kernel-image-2.4.17-ia64
    Vulnerability  : missing function return value check
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : CAN-2004-0077
    
    Paul Starzetz and Wojciech Purczynski of isec.pl discovered a critical
    security vulnerability in the memory management code of Linux inside
    the mremap(2) system call.  Due to missing function return value check
    of internal functions a local attacker can gain root privileges.
    
    For the stable distribution (woody) this problem has been fixed in
    version 011226.16 of ia64 kernel source and images.
    
    Other architectures are or will be mentioned in a separate advisory
    respectively or are not affected (m68k).
    
    For the unstable distribution (sid) this problem will be fixed in version
    2.4.24-3.
    
    This problem is also fixed in the upstream version of Linux 2.4.25 and
    2.6.3.
    
    We recommend that you upgrade your Linux kernel packages immediately.
