1. Summary:
Updated policycoreutils packages that fix one security issue are now

important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

3. Description:
The policycoreutils packages contain the core utilities that are
required for the basic operation of a Security-Enhanced Linux (SELinux)
system and its policies.
It was discovered that the seunshare utility did not enforce proper file
permissions on the directory used as an alternate temporary directory
mounted as /tmp/. A local user could use this flaw to overwrite files or,
possibly, execute arbitrary code with the privileges of a setuid or
setgid application that relies on proper /tmp/ permissions, by running that
application via seunshare. (CVE-2011-1011)
Red Hat would like to thank Tavis Ormandy for reporting this issue.
This update also introduces the following changes:
* The seunshare utility was moved from the main policycoreutils subpackage
to the policycoreutils-sandbox subpackage. This utility is only required
by the sandbox feature and does not need to be installed by default.
* Updated selinux-policy packages that add the SELinux policy changes
required by the seunshare fixes.
All policycoreutils users should upgrade to these updated packages, which
correct this issue.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
