This update incorporates fixes from upstream which correct integer underflow problems in the AES and RC4 decryption routines (CVE-2009-4212). It also corrects a failure in ‘kdb5_util load’ which could occur when the database files being created did not previously exist.

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.
