Scientific Linux Security Update : policycoreutils on SL6.x i386/x86_64
medium Nessus Plugin ID 61009
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.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)
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.
