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. thunderbird priority reduced sinct it requires javascript be enabled ## References * [MITRE](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1840) * [NVD](https://nvd.nist.gov/vuln/detail/CVE-2009-1840) * [Launchpad](https://launchpad.net/bugs/cve/CVE-2009-1840) * [Debian](https://security-tracker.debian.org/tracker/CVE-2009-1840) ### Related Ubuntu Security Notices (USN) + [USN-779-1](https://usn.ubuntu.com/USN-779-1) + Firefox and Xulrunner vulnerabilities + 12 June 2009 ### Other references *
