Fedora 13 : krb5-1.7.1-7.fc13 (2010-4608)
Medium Nessus Plugin ID 47366
SynopsisThe remote Fedora host is missing a security update.
DescriptionA 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.
SolutionUpdate the affected krb5 package.
