Details

A bug was discovered in the XFS filesystem's 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)
