    Package        : dietlibc
    Vulnerability  : integer overflow
    Problem-Type   : remote
    Debian-specific: no
    CVE Id         : CAN-2002-0391
    CERT advisory  : VU#192995
    
    An integer overflow bug has been discovered in the RPC library used by
    dietlibc, a libc optimized for small size, which is derived from the
    SunRPC library.  This bug could be exploited to gain unauthorized root
    access to software linking to this code.  The packages below also fix
    integer overflows in the calloc, fread and fwrite code.  They are also
    more strict regarding hostile DNS packets that could lead to a
    vulnerability otherwise.
    
    These problems have been fixed in version 0.12-2.2 for the current
    stable distribution (woody) and in version 0.20-0cvs20020806 for the
    unstable distribution (sid).  Debian 2.2 (potato) is not affected
    since it doesn't contain dietlibc packages.
    
    We recommend that you upgrade your dietlibc packages immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
