Several remote vulnerabilities have been discovered in Xulrunner, a runtime environment for XUL applications. The Common Vulnerabilities and Exposures project identifies the following problems:
Ronen Zilberman and Michal Zalewski discovered that a timing race allows the injection of content into about:blank frames.
Michal Zalewski discovered that same-origin policies for wyciwyg:// documents are insufficiently enforced.
Bernd Mielke, Boris Zbarsky, David Baron, Daniel Veditz, Jesse Ruderman, Lukas Loehrer, Martijn Wargers, Mats Palmgren, Olli Pettay, Paul Nickerson and Vladimir Sukhoy discovered crashes in the layout engine, which might allow the execution of arbitrary code.
moz_bug_r_a4 discovered that the addEventListener() and setTimeout() functions allow cross-site scripting.
moz_bug_r_a4 discovered that a programming error in event handling allows privilege escalation.
shutdown and moz_bug_r_a4 discovered that the XPCNativeWrapper allows the execution of arbitrary code.
The oldstable distribution (sarge) doesn't include xulrunner.
For the stable distribution (etch) these problems have been fixed in version 184.108.40.206~pre070720-0etch1. A build for the mips architecture is not yet available, it will be provided later.
For the unstable distribution (sid) these problems have been fixed in version 220.127.116.11-1.
We recommend that you upgrade your xulrunner packages.
