Fedora 9 : krb5-1.6.3-16.fc9 (2009-2834)

critical Nessus Plugin ID 36108

Synopsis

The remote Fedora host is missing a security update.

Description

This update incorporates patches to fix potential read overflow and NULL pointer dereferences in the implementation of the SPNEGO GSSAPI mechanism (CVE-2009-0844, CVE-2009-0845), attempts to free an uninitialized pointer during protocol parsing (CVE-2009-0846), and a bug in length validation during protocol parsing (CVE-2009-0847).

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.

Solution

Update the affected krb5 package.
