Description

The policycoreutils packages contain the core utilities that arerequired 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 filepermissions on the directory used as an alternate temporary directorymounted as /tmp/. A local user could use this flaw to overwrite files or,possibly, execute arbitrary code with the privileges of a setuid orsetgid application that relies on proper /tmp/ permissions, by running thatapplication via seunshare. (CVE-2011-1011)Red Hat would like to thank Tavis Ormandy for reporting this issue.This update also introduces the following changes:All policycoreutils users should upgrade to these updated packages, whichcorrect this issue.
