Fossil: User-assisted execution of arbitrary code

Background

Fossil is a simple, high-reliability, distributed software configuration management system.

Description

Fossil does not properly validate SSH sync protocol URLs.

Impact

A remote attacker, by enticing a user to open a specially crafted URL, could possibly execute arbitrary commands with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All Fossil users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-vcs/fossil-2.4"
