NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

Mozilla Firefox before 3.6.7 and Thunderbird before 3.1.1 do not properly implement read restrictions for CANVAS elements, which allows remote attackers to obtain sensitive cross-origin information via vectors involving reference retention and node deletion.
