Several remote vulnerabilities have been discovered in Xulrunner, a runtime environment for XUL applications. The Common Vulnerabilities and Exposures project identifies the following problems:
It was discovered that missing boundary checks on a reference counter for CSS objects can lead to the execution of arbitrary code.
Devon Hubbard, Jesse Ruderman and Martijn Wargers discovered crashes in the layout engine, which might allow the execution of arbitrary code.
moz_bug_r_a4 discovered several cross-site scripting vulnerabilities.
moz_bug_r_a4 discovered that XUL documents can escalate privileges by accessing the pre-compiled fastload file.
moz_bug_r_a4 discovered that missing input sanitising in the mozIJSSubScriptLoader.loadSubScript() function could lead to the execution of arbitrary code. Iceweasel itself is not affected, but some addons are.
Claudio Santambrogio discovered that missing access validation in DOM parsing allows malicious web sites to force the browser to upload local files to the server, which could lead to information disclosure.
Daniel Glazman discovered that a programming error in the code for parsing .properties files could lead to memory content being exposed to addons, which could lead to information disclosure.
Masahiro Yamada discovered that file URLs in directory listings were insufficiently escaped.
John G. Myers, Frank Benkstein and Nils Toedtmann discovered that alternate names on self-signed certificates were handled insufficiently, which could lead to spoofing of secure connections.
Greg McManus discovered a crash in the block reflow code, which might allow the execution of arbitrary code.
Billy Rios discovered that passing an URL containing a pipe symbol to Iceweasel can lead to Chrome privilege escalation.
For the stable distribution (etch), these problems have been fixed in version 188.8.131.52~pre080614d-0etch1.
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.
