Test ID:	1.3.6.1.4.1.25623.1.0.67199
Category:	Fedora Local Security Checks
Title:	Fedora Core 13 FEDORA-2010-4608 (krb5)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to krb5 announced via advisory FEDORA-2010-4608. 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.

This update can be installed with the yum update program. Use su -c 'yum update krb5' at the command line.
