CVE-2010-1121 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 5.73% chance of exploitation in the next 30 days.
