Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-ti-omap4: Linux kernel for OMAP4

Details:

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 the b43 driver in the Linux kernel. An attacker could

use this flaw to cause a denial of service if the system has an active

wireless interface using the b43 driver. (CVE-2011-3359)
