FreeBSD : sudo -- Flaw in Runas group matching (67b514c3-ba8f-11df-8f6e-000c29a67389)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Todd Miller reports :

Beginning with sudo version 1.7.0 it has been possible to grant
permission to run a command using a specified group via sudo -g option
(run as group). A flaw exists in the logic that matches Runas groups
in the sudoers file when the -u option is also specified (run as
user). This flaw results in a positive match for the user specified
via -u so long as the group specified via -g is allowed by the sudoers

Exploitation of the flaw requires that Sudo be configured with sudoers
entries that contain a Runas group. Entries that do not contain a
Runas group, or only contain a Runas user are not affected.
