RHSA-2010:0122: Important: sudo security update
The sudo (superuser do) utility allows system administrators to givecertain users the ability to run commands as root.A privilege escalation flaw was found in the way sudo handled the sudoeditpseudo-command. If a local user were authorized by the sudoers file to usethis pseudo-command, they could possibly leverage this flaw to executearbitrary code with the privileges of the root user. (CVE-2010-0426)The sudo utility did not properly initialize supplementary groups when the"runasdefault" option (in the sudoers file) was used. If a local userwere authorized by the sudoers file to perform their sudo commands underthe account specified with "runasdefault", they would receive the rootuser's supplementary groups instead of those of the intended target user,giving them unintended privileges. (CVE-2010-0427)Users of sudo should upgrade to this updated package, which containsbackported patches to correct these issues.
