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"
|
