Details

Florian Weimer discovered that UDisks incorrectly handled certain long path
names. A local attacker could use this issue to cause udisks to crash,
resulting in a denial of service, or possibly execute arbitrary code.
The default compiler options for affected releases should reduce the
vulnerability to a denial of service.
