Description Josh Bressers 2005-01-04 22:58:26 UTC 
*** This bug has been split off bug 142902 ***

------- Original comment by Josh Bressers (Security Response Team) on 2004.12.14

secalert received a message from the MIT Kerberos Development Team
detailing a vulnerability.

The MIT Kerberos 5 administration library (libkadm5srv) contains a
heap buffer overflow in password history handling code which could be
exploited to execute arbitrary code on a Key Distribution Center (KDC)
host.  The overflow occurs during a password change of a principal
with a certain password history state.  An administrator must have
performed a certain password policy change in order to create the
vulnerable state.

There is currently no patch for this issue.  I'll attach one as soon
as it becomes available.

The MIT team wants to realease their update sometimes around
2004-12-21 since this issue is technically public (we are however
treating it as embargoed).
