SuSE Update for AppArmor SUSE-SA:2007:015

Check for the Version of AppArmor

Two new language features have been added to improve the confinement provided to applications executing other applications will confined by AppArmor. - Two new execute modifiers: 'P' and 'U' are provided and are flavors of the existing 'p' and 'u' modifiers but indicate that the environment should be stripped across the execute transition. Using &quot Ux&quot and &quot Px&quot avoids injecting code using LD_PRELOAD and similar variables into the started executables by a infected profiled program. The environment variable filtering is the same as used for setuid applications. - A new permission 'm' is required when an application executes mmap(2) with protection PROT_EXEC. This avoids infected binaries escalating the &quot r&quot privilege to a file into a &quot rx&quot privilege. Note that both issues are not directly security fixes, they instead avoid common problems during profile creation. These changes also require a new kernel, which we released in December 2006, tracked by our advisory SUSE-SA:2006:079. Only SUSE Linux Enterprise Server 9 (and related products) and SUSE Linux 10.0 are affected by this change. SUSE Linux 10.1, SUSE Linux Enterprise 10 and newer products already contain the new profile syntax and behavior.
