A bug was discovered in the XFS filesystemâs handling of pathnames. A local attacker could exploit this to crash the system, leading to a denial of service, or gain root privileges. (CVE-2011-4077)
A flaw was found in the Journaling Block Device (JBD). A local attacker able to mount ext3 or ext4 file systems could exploit this to crash the system, leading to a denial of service. (CVE-2011-4132)
Clement Lecigne discovered a bug in the HFS file system bounds checking. When a malformed HFS file system is mounted a local user could crash the system or gain root privileges. (CVE-2011-4330).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
