Zusammenfassung:	NOSUMMARY
Beschreibung:	Description: The remote host is missing updates announced in advisory RHSA-2011:0414. 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. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2011-0414.html Risk factor : High CVSS Score: 6.9
