Fedora 8 : krb5-1.6.2-14.fc8 (2008-2647)

critical Nessus Plugin ID 31670


The remote Fedora host is missing a security update.


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. This update also fixes an incorrect calculation of the length of the absolute path name of a file when the relative path is known and the library needs to look up which SELinux label to apply to the file.

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 package.
