Several remote vulnerabilities have been discovered in Xulrunner, a
runtime environment for XUL applications. The Common Vulnerabilities
and Exposures project identifies the following problems:
- CVE-2007-1095
Michal Zalewski discovered that the unload event handler had access to
the address of the next page to be loaded, which could allow information
disclosure or spoofing.
- CVE-2007-2292
Stefano Di Paola discovered that insufficient validation of user names
used in Digest authentication on a web site allows HTTP response splitting
attacks.
- CVE-2007-3511

control can lead to information disclosure. This is a variant of
CVE-2006-2894.
- CVE-2007-5334

titlebar of windows, which can lead to spoofing attacks.
- CVE-2007-5337

The oldstable distribution (sarge) doesnโt contain xulrunner.
For the stable distribution (etch) these problems have been fixed in version
1.8.0.14~pre071019b-0etch1. Builds for hppa and mipsel will be provided later.
For the unstable distribution (sid) these problems will be fixed soon.
We recommend that you upgrade your xulrunner packages.
