Fedora 13 : krb5-1.7.1-7.fc13 (2010-4608)

Synopsis :

The remote Fedora host is missing a security update.

Description :

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.

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.
