news 28 Posted September 7, 2010 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: sudo security update Advisory ID: RHSA-2010:0675-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0675.html Issue date: 2010-09-07 CVE Names: CVE-2010-2956 ===================================================================== 1. Summary: An updated sudo package that fixes one security issue is now available for Red Hat Enterprise Linux 5. 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 (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: The sudo (superuser do) utility allows system administrators to give certain users the ability to run commands as root. A flaw was found in the way sudo handled Runas specifications containing both a user and a group list. If a local user were authorized by the sudoers file to perform their sudo commands with the privileges of a specified user and group, they could use this flaw to run those commands with the privileges of either an arbitrary user or group on the system. (CVE-2010-2956) Red Hat would like to thank Markus Wuethrich of Swiss Post - PostFinance for reporting this issue. Users of sudo should upgrade to this updated package, which contains a backported patch to correct this issue. 4.
