Description David Walser 2013-03-01 16:39:35 CET

Upstream has released krb5 1.11.1, which fixes a security issue:
http://web.mit.edu/kerberos/krb5-1.11/

Updated package uploaded for Cauldron.

Patched package uploaded for Mageia 2.

Patch checked into Mageia 1 SVN.

Advisory:
========================

Updated krb5 packages fix security vulnerability:

It was reported that the KDC plugin for PKINIT could dereference a NULL
pointer when a malformed packet caused processing to terminate early, which
led to a crash of the KDC process.  An attacker would require a valid PKINIT
certificate or have observed a successful PKINIT authentication to execute a
successful attack.  In addition, an unauthenticated attacker could execute
the attack of anonymouse PKINIT was enabled (CVE-2013-1415).
