selinux-policy-3.7.19-54.AXS4.5, policycoreutils-2.0.83-19.8.AXS4

Security-enhanced Linux is a feature of the Linux® kernel and a number of utilities with enhanced security functionality designed to add mandatory access controls to Linux. The Security-enhanced Linux kernel contains new architectural components originally developed to improve the security of the Flask operating system. These architectural components provide general support for the enforcement of many kinds of mandatory access control policies, including those based on the concepts of Type Enforcement®, Role-based Access Control, and Multi-level Security.
policycoreutils contains the policy core utilities that are required for basic operation of a SELinux system. These utilities include load_policy to load policies, setfiles to label filesystems, newrole to switch roles, and run_init to run /etc/init.d scripts in the proper context.
Security issues fixed with this release:
CVE-2011-1011
The seunshare_mount function in sandbox/seunshare.c in seunshare in certain Asianux packages of policycoreutils 2.0.83 and earlier in Asianux Server 4 and earlier, mounts a new directory on top of /tmp without assigning root ownership and the sticky bit to this new directory, which allows local users to replace or delete arbitrary /tmp files, and consequently cause a denial of service or possibly gain privileges, by running a setuid application that relies on /tmp, as demonstrated by the ksu application.
