Description

This updates to the latest upstream stable kernel (2.6.18.2), and also fixes a number of security issues.

MOKB-05-11-2006: Linux 2.6.x ISO9660 __find_get_block_slow() denial of service http://projects.info-pull.com/mokb/MOKB-05-11-2006.html (CVE-2006-5757)

MOKB-07-11-2006: Linux 2.6.x zlib_inflate memory corruption http://projects.info-pull.com/mokb/MOKB-07-11-2006.html

MOKB-09-11-2006: Linux 2.6.x ext3fs_dirhash denial of service http://projects.info-pull.com/mokb/MOKB-10-11-2006.html

Herbert Xu found a security issue in the Xen hypervisor, which would allow a malicious guest to access a freed grant table page after freeing and possibly having it reallocated to another guest.

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.
