kernel: multiple vulnerabilities

Package(s):kernel CVE #(s):CVE-2011-4131 CVE-2011-4132
Created:November 21, 2011 Updated:July 10, 2012
Description: From the Red Hat bugzilla:

nfs4_getfacl decoding causes a kernel Oops when a server returns more than 2 GETATTR bitmap words in response to the FATTR4_ACL attribute request.

While the NFS client only asks for one attribute (FATTR4_ACL) in the first bitmap word, the NFSv4 protocol allows for the server to return unbounded bitmaps.

From the Red Hat bugzilla:

A flaw was found in the way Linux kernel's Journaling Block Device (JBD) handled invalid log first block value. An attacker able to mount malicious ext3 or ext4 image could use this flaw to crash the system.
