    Package        : cvs
    Vulnerability  : doubly freed memory
    Problem-Type   : remote
    Debian-specific: no
    CVE Id         : CAN-2003-0015
    
    Stefan Esser discovered a problem in cvs, a concurrent versions
    system, which is used for many Free Software projects.  The current
    version contais a flaw that can be used by a remote attacker to
    execute arbitrary code on the CVS server under the user id the CVS
    server runs as.  Anonymous read-only access is sufficient to exploit
    this problem.
    
    For the stable distribution (woody) this problem has been
    fixed in version 1.11.1p1debian-8.1.
    
    For the old stable distribution (potato) this problem has been fixed
    in version 1.10.7-9.2.
    
    For the unstable distribution (sid) this problem will be fixed soon.
    
    We recommend that you upgrade your cvs package immediately.
