Fedora 7 : krb5-1.6.1-9.fc7 (2008-2637)

critical Nessus Plugin ID 31668

Synopsis

The remote Fedora host is missing a security update.

Description

This update incorporates fixes included in MITKRB5-SA-2008-001 (use of uninitialized pointer / double-free in the KDC when v4 compatibility is enabled) and MITKRB5-SA-2008-002 (incorrect handling of high-numbered descriptors in the RPC library). This update also incorporates less-critical fixes for a double- free (CVE-2007-5971) and an incorrect attempt to free non-heap memory (CVE-2007-5901) in the GSSAPI library.

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.
