A vulnerability in sudo may allow for privilege escalation.
sudo allows a system administrator to give users the ability to run commands as other users.
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.
A local attacker could possibly run commands as an arbitrary system user (including root).
There is no known workaround at this time.
All sudo users should upgrade to the latest version:
