Several remote vulnerabilities have been discovered in Xulrunner, a runtime environment for XUL applications, such as the Iceweasel web browser. The Common Vulnerabilities and Exposures project identifies the following problems:
Vladimir Vukicevic, Jesse Ruderman, Martijn Wargers, Daniel Banchero, David Keeler and Boris Zbarsky reported crashes in layout engine, which might allow the execution of arbitrary code.
Carsten Book reported a crash in the layout engine, which might allow the execution of arbitrary code.
Jesse Ruderman and Sid Stamm discovered spoofing vulnerability in the file download dialog.
Gregory Fleischer discovered a bypass of the same-origin policy using the document.getSelection() function.
"moz_bug_r_a4" discovered a privilege escalation to Chrome status in the XPCOM utility XPCVariant::VariantDataToJS.
"regenrecht" discovered a buffer overflow in the GIF parser, which might lead to the execution of arbitrary code.
Marco C. discovered that a programming error in the proxy auto configuration code might lead to denial of service or the execution of arbitrary code.
Jeremy Brown discovered that the filename of a downloaded file which is opened by the user is predictable, which might lead to tricking the user into a malicious file if the attacker has local access to the system.
Paul Stone discovered that history information from web forms could be stolen.
For the stable distribution (lenny), these problems have been fixed in version 188.8.131.52-0lenny1.
As indicated in the Etch release notes, security support for the Mozilla products in the oldstable distribution needed to be stopped before the end of the regular Etch security maintenance life cycle. You are strongly encouraged to upgrade to stable or switch to a still supported browser.
For the unstable distribution (sid), these problems have been fixed in version 184.108.40.206-1.
We recommend that you upgrade your xulrunner packages.
