USN-1330-1: Linux kernel (OMAP4) vulnerabilities

First published: Fri Jan 13 2012(Updated: )

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) 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) Chen Haogang discovered an integer overflow that could result in memory corruption. A local unprivileged user could use this to crash the system. (CVE-2012-0044)
