Summary

The JavaScript engine in Mozilla Firefox before 2.0.0.14, Thunderbird before 2.0.0.14, and SeaMonkey before 1.1.10 allows remote attackers to cause a denial of service (garbage collector crash) and possibly have other impacts via a crafted web page. NOTE: this is due to an incorrect fix for CVE-2008-1237.
