    Package        : dietlibc
    Vulnerability  : integer overflow
    Problem-Type   : remote
    Debian-specific: no
    CVE Id         : CAN-2003-0028
    CERT advisory  : VU#516825 CA-2003-10
    
    eEye Digital Security discovered an integer overflow in the
    xdrmem_getbytes() function of glibc, that is also present in dietlibc,
    a small libc useful especially for small and embedded systems.  This
    function is part of the XDR encoder/decoder derived from Sun's RPC
    implementation.  Depending upon the application, this vulnerability
    can cause buffer overflows and could possibly be exploited to execute
    arbitray code.
    
    For the stable distribution (woody) this problem has been
    fixed in version 0.12-2.5.
    
    The old stable distribution (potato) does not contain dietlibc
    packages.
    
    For the unstable distribution (sid) this problem has been
    fixed in version 0.22-2.
    
    We recommend that you upgrade your dietlibc packages.
