    Package        : calife
    Vulnerability  : buffer overflow
    Problem-Type   : local
    Debian-specific: no
    CVE Ids        : CAN-2004-0188
    Debian bug     : 235157
    
    Calife, a program which provides super user privileges to specific
    users, was found to contain a buffer overflow related to the
    getpass(3) library function.  A local attacker could potentially
    exploit this vulnerability, given knowledge of a local user's password
    and the presence of at least one entry in /etc/calife.auth, to execute
    arbitrary code with root privileges.
    
    For the current stable distribution (woody) this problem has been
    fixed in version 2.8.4c-1woody1.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 2.8.6-1.
    
    We recommend that you update your calife package.
