Name        : krb5
Product     : Fedora 13
Version     : 1.7.1
Release     : 7.fc13
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:

A GSSAPI-authenticated service could be remotely forced to trigger an assertion
failure by sending it certain invalid messages (MITKRB5-SA-2010-002,
CVE-2010-0628).    The included patch for adding PAM support to the bundled FTP
server contained a bug which would cause the service to crash if a client
attempted to authenticate as a user who was not known to the server system.  In
the default xinetd configuration, the service would be invoked with the -a flag,
and this would therefore only be possible if the client authenticated using
GSSAPI beforehand.
