Sudo vulnerability

Releases

Details

Markus Wuethrich discovered that sudo did not always verify the user when a
group was specified in the Runas_Spec. A local attacker could exploit this
to execute arbitrary code as root if sudo was configured to allow the
attacker to use a program as a group when the attacker was not a part of
that group.
