CVE-2010-2768

Published: 7 September 2010

Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 do not properly restrict use of the type attribute of an OBJECT element to set a document's charset, which allows remote attackers to bypass cross-site scripting (XSS) protection mechanisms via UTF-7 encoding.

Notes

CVEs in Firefox are tracked in the xulrunner source packages for
builds that use the system xulrunner, and firefox source packages for those
that use a static build
xulrunner (1.8.0): firefox (1.5) - Ubuntu 6.06 LTS (system xul)
xulrunner (1.8.1): firefox (2.0) - Ubuntu 6.10 - 8.04 LTS (system xul)
xulrunner-1.9: (ignored) reverse dependencies no longer process web content
xulrunner-1.9.1: (ignored) reverese dependencies no longer process web content
xulrunner-1.9.2: system xul for reverese dependencies that process web content
firefox: Ubuntu 6.06 LTS (static build)
firefox: Ubuntu 10.04 LTS and higher (static build of 3.6.x or higher)
firefox-3.0: Ubuntu 8.04 LTS, 9.04 (static build of 3.6.x)
firefox-3.5: Ubuntu 9.04 (ignored, uses system xul 1.9.1. Use 3.0 instead)
firefox-3.5: Ubuntu 9.10 (static build of 3.6.x)
