FAUCET Score

CVE-2010-1209 describes a use-after-free vulnerability in the NodeIterator implementation of Mozilla Firefox versions 3.5.x and 3.6.x, and SeaMonkey before 2.0.6. This critical vulnerability, rated 9.3 CVSS, allows remote attackers to execute arbitrary code through a crafted NodeFilter that detaches DOM nodes, requiring medium attack complexity but no authentication.
