Name        : krb5
Product     : Fedora 7
Version     : 1.6.1
Release     : 9.fc7
URL         : http://web.mit.edu/kerberos/www/
Summary     : The Kerberos network authentication system.
Description :
Kerberos V5 is a trusted-third-party network authentication system,
which can improve your network's security by eliminating the insecure
practice of cleartext passwords.

Update Information:

This update incorporates fixes included in MITKRB5-SA-2008-001 (use of
uninitialized pointer / double-free in the KDC when v4 compatibility is enabled)
and MITKRB5-SA-2008-002 (incorrect handling of high-numbered descriptors in the
RPC library).    This update also incorporates less-critical fixes for a double-
free (CVE-2007-5971) and an incorrect attempt to free non-heap memory
(CVE-2007-5901) in the GSSAPI library.
