Peter Huewe discovered an information leak in the handling of reading security-related TPM data. A local, unprivileged user could read the results of a previous TPM command. (CVE-2011-1162)
Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. (CVE-2011-2203)
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).
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.
