-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Important: polkit security update Advisory ID: RHSA-2013:1270-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2013:1270.html Issue date: 2013-09-19 CVE Names: CVE-2013-4288 ==================================================================== 1. Summary: Updated polkit packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 3. Description: PolicyKit is a toolkit for defining and handling authorizations. A race condition was found in the way the PolicyKit pkcheck utility checked process authorization when the process was specified by its process ID via the --process option. A local user could use this flaw to bypass intended PolicyKit authorizations and escalate their privileges. (CVE-2013-4288) Note: Applications that invoke pkcheck with the --process option need to be modified to use the pid,pid-start-time,uid argument for that option, to allow pkcheck to check process authorization correctly. Red Hat would like to thank Sebastian Krahmer of the SUSE Security Team for reporting this issue. All polkit users should upgrade to these updated packages, which contain a backported patch to correct this issue. The system must be rebooted for this update to take effect. 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 https://access.redhat.com/site/articles/11258 5.
