CVE-2011-0006

Published: 12 January 2012

The ima_lsm_rule_init function in security/integrity/ima/ima_policy.c in the Linux kernel before 2.6.37, when the Linux Security Modules (LSM) framework is disabled, allows local users to bypass Integrity Measurement Architecture (IMA) rules in opportunistic circumstances by leveraging an administrator's addition of an IMA rule for LSM.

From the Ubuntu security team

A flaw was found in the kernel's Integrity Measurement Architecture (IMA). Changes made by an attacker might not be discovered by IMA, if SELinux was disabled, and a new IMA rule was loaded.
