tag_insight = "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.

We recommend that you upgrade your libpam-heimdal package.";
