Fedora 16 : krb5-appl-1.0.2-2.fc16 (2011-17493)

Critical Nessus Plugin ID 57443


The remote Fedora host is missing a security update.


This update incorporates the upstream patch to fix a buffer overflow in the Kerberos-aware telnet server.

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.


Update the affected krb5-appl package.
