Several remote vulnerabilities have been discovered in the Iceweasel web browser, an unbranded version of the Firefox browser. The Common Vulnerabilities and Exposures project identifies the following problems:
Nicolas Derouet discovered that Iceweasel performs insufficient validation of cookies, which could lead to denial of service.
Boris Zbarsky, Eli Friedman, Georgi Guninski, Jesse Ruderman, Martijn Wargers and Olli Pettay discovered crashes in the layout engine, which might allow the execution of arbitrary code.
Brendan Eich, Igor Bukanov, Jesse Ruderman, moz_bug_r_a4
and Wladimir Palant
discovered crashes in the javascript engine, which might allow the execution of
arbitrary code.
Marcel
discovered that malicous web sites can cause massive
resource consumption through the auto completion feature, resulting
in denial of service.
moz_bug_r_a4
discovered that adding an event listener through the
addEventListener() function allows cross-site scripting.
Chris Thomas discovered that XUL popups can be abused for spoofing or phishing attacks.
Fixes for the oldstable distribution (sarge) are not available. While there will be another round of security updates for Mozilla products, Debian doesn't have the resources to backport further security fixes to the old Mozilla products. You're strongly encouraged to upgrade to stable as soon as possible.
For the stable distribution (etch) these problems have been fixed in version 2.0.0.4-0etch1. A build for the Alpha architecture is not yet available, it will be provided later.
For the unstable distribution (sid) these problems have been fixed in version 2.0.0.4-1.
We recommend that you upgrade your iceweasel packages.
MD5 checksums of the listed files are available in the original advisory.
