Red Hat: 2010:0675-01: sudo: Important Advisory
Summary
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.
