Severity: High Title: sudo: Privilege escalation Date: February 06, 2009 Bugs: #256633 ID: 200902-01

Synopsis ========
A vulnerability in sudo may allow for privilege escalation.
Background ==========
sudo allows a system administrator to give users the ability to run commands as other users.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/sudo < 1.7.0 >=3D 1.7.0
Description ===========
Harald Koenig discovered that sudo incorrectly handles group specifications in Runas_Alias (and related) entries when a group is specified in the list (using %group syntax, to allow a user to run commands as any member of that group) and the user is already a member of that group.
Impact ======
A local attacker could possibly run commands as an arbitrary system user (including root).
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All sudo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dapp-admin/sudo-1.7.0"
References ==========
