Debian DSA-735-1 : sudo - pathname validation race

low Nessus Plugin ID 18603

Synopsis

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

Description

A local user who has been granted permission to run commands via sudo could run arbitrary commands as a privileged user due to a flaw in sudo's pathname validation. This bug only affects configurations which have restricted user configurations prior to an ALL directive in the configuration file. A workaround is to move any ALL directives to the beginning of the sudoers file; see the advisory at for more information.

Solution

Upgrade the sudo package.

For the old stable Debian distribution (woody), this problem has been fixed in version 1.6.6-1.3woody1.

For the current stable distribution (sarge), this problem has been fixed in version 1.6.8p7-1.1sarge1.

Note that packages are not yet ready for certain architectures; these will be released as they become available.
