CVE-2010-1121

Published: 25 March 2010

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.

Notes

AuthorNote
jdstrand
CVEs in Firefox are tracked in the xulrunner source packages. The
mapping of xulrunner sources to firefox is:
xulrunner (1.8.0): firefox (1.5) - Ubuntu 6.06 LTS
xulrunner (1.8.1): firefox (2.0) - Ubuntu 6.10 - 8.04 LTS
xulrunner-1.9: firefox-3.0
xulrunner-1.9.1: firefox-3.5
Ubuntu 6.06 LTS and 10.04 LTS uses the embedded xulrunner and not
the system xulrunner-1.9.2, so it is tracked in the firefox source package.
