Synopsis :

The remote Mandrake Linux host is missing one or more security
updates.

Description :

A stack-based buffer overflow vulnerability was discovered in the RPC
library used by Kerberos' kadmind program by Tenable Network Security.
A remote unauthenticated user who could access kadmind would be able
to trigger the flaw and cause it to crash (CVE-2007-3999). This issue
is only applicable to Kerberos 1.4 and higher.

Garrett Wollman found an uninitialized pointer vulnerability in
kadmind which a remote unauthenticated attacker able to access kadmind
could exploit to cause kadmind to crash (CVE-2007-4000). This issue is
only applicable to Kerberos 1.5 and higher.

Update :

The MIT Kerberos Team found a problem with the originally published
patch for CVE-2007-3999. A remote unauthenticated attacker able to
access kadmind could trigger this flaw and cause kadmind to crash.

Updated packages have been patched to prevent these issues.
