Description Vincent Danen 2012-08-14 18:43:08 EDT

Florian Weimer of the Red Hat Product Security Team discovered that Condor's file system authentication challenge accepted directories with weak permissions (for example, world readable, writable and executable permissions). If a user created a directory with such permissions, a local attacker could rename it, allowing them to execute jobs with the privileges of the victim user.
