This vulnerability has been assigned ID <a href="https://access.redhat.com/security/cve/CVE-2010-1205">CVE-2010-1205</a> (via Mozilla). An additional memory-leak bug, involving images with malformed sCAL chunks, is also present; it could lead to an application crash (denial of service) when viewing such images.
