Mozilla Firefox 3.6.x before 3.6.3 does not properly manage the scopes of DOM nodes that are moved from one document to another, which allows remote attackers to conduct use-after-free attacks and execute arbitrary code via unspecified vectors involving improper interaction with garbage collection, as demonstrated by Nils during a Pwn2Own competition at CanSecWest 2010.

Security readout for executives and security teams

CVE-2010-1121 is an old Firefox memory-safety flaw. A malicious web page could trigger incorrect handling of moved DOM nodes and potentially run code on the user's machine. The issue affected Firefox 3.6.x before 3.6.3. It is mainly relevant to legacy systems, frozen images, or unmanaged endpoints. Exposure is likely limited to environments still running Firefox 3.6.x before 3.6.3 or old Linux distribution packages referenced by vendor advisories. Modern supported Firefox versions are not identified as affected in the provided sources. Treat as high priority only where legacy Firefox remains. The business risk is remote code execution through browsing, but exposure should be narrow in current environments. Prioritize asset discovery and removal of obsolete browser versions. Mitigation focus: Upgrade Firefox 3.6.x systems to Firefox 3.6.3 or later.; Apply applicable vendor updates from Ubuntu, Red Hat, Fedora, or SUSE advisories.; Remove legacy browser builds from unmanaged endpoints and golden images..
