    Derek Chan discovered that the PAM module for the Heimdal Kerberos
    implementation allows reinitialisation of user credentials when run
    from a setuid context, resulting in potential local denial of service
    by overwriting the credential cache file or to local privilege
    escalation.
    
    For the stable distribution (etch), this problem has been fixed in
    version 2.5-1etch1.
    
    For the upcoming stable distribution (lenny), this problem has been
    fixed in version 3.10-2.1.
    
    For the unstable distribution (sid), this problem will be fixed soon.
