Synopsis

TORQUE creates temporary files in an insecure manner which could lead to the execution of arbitrary code with elevated privileges.

2.  Impact Information

Background

TORQUE is a resource manager providing control over batch jobs and distributed compute nodes.

Description

TORQUE creates temporary files with predictable names. Please note that the TORQUE package shipped in Gentoo Portage is not vulnerable in the default configuration. Only systems with more permissive access rights to the spool directory are vulnerable.

Impact

A local attacker could create links in the temporary file directory, pointing to a valid file somewhere on the filesystem. This could lead to the execution of arbitrary code with elevated privileges.

3.  Resolution Information

Workaround

Ensure that untrusted users don't have write access to the spool directory.

Resolution

All TORQUE users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-cluster/torque-2.1.6"
