Debian Linux Security Advisory 2699-1 - Multiple security issues have been found in Iceweasel, Debian's version of the Mozilla Firefox web browser. These issues include multiple memory safety errors, missing input sanitizing vulnerabilities, use-after-free vulnerabilities, buffer overflows and other programming errors which may lead to the execution of arbitrary code, privilege escalation, information leaks or cross site scripting.

Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code. Security researcher Cody Crews reported a method to call a content level constructor that allows for this constructor to have chrome privileged access. This affects chrome object wrappers and allows for write actions on objects when only read actions should be allowed. This can lead to cross-site scripting attacks. Various other issues have also been addressed.

If the user were tricked into opening a specially crafted message with scripting enabled, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Thunderbird. CVE-2013-1669) Cody Crews discovered that some constructors could be used to bypass restrictions enforced by their Chrome Object Wrapper (COW). If a user had scripting enabled, an attacker could exploit this to conduct cross-site scripting (XSS) attacks. Various other issues were also addressed.
