CVE-2010-2956

First published: Mon Aug 30 2010(Updated: )

A security flaw was found in the way Sudo performed matching for user described by a password against the list of members, allowed to run particular sudo command, when the group option was specified on the command line. If a local, unprivileged user was authorized by sudoers file to run their sudo commands with permissions of a particular group (different to their own), it could lead to privilege escalation (execution of that sudo command with permissions of privileged user account (root)). Acknowledgements: Red Hat would like to thank Markus Wuethrich of Swiss Post - PostFinance for reporting this issue.
