Descripción: | Description: The remote host is missing an update to linux-image-3.0.0-15-generic announced via advisory USN-1322-1.
Details:
Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. (CVE-2011-2203)
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)
Nick Bowler discovered the kernel GHASH message digest algorithm incorrectly handled error conditions. A local attacker could exploit this to cause a kernel oops. (CVE-2011-4081)
A flaw was found in how the Linux kernel handles user-defined key types. An unprivileged local user could exploit this to crash the system. (CVE-2011-4110)
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)
