Fedora 19 : krb5-1.11.2-6.fc19 (2013-8113)

Description

This update pulls in the upstream fix for a UDP ping-pong vulnerability in the kpasswd service provided by kadmind (CVE-2002-2443), and modifies the client library to treat KRB5CCNAME values which begin with 'DIR::' in a way that's almost the same as the way it treats values which begin with 'DIR:'.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
