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:
moz_bug_r_a4 discovered that a regression in the handling of about:blank windows used by addons may lead to an attacker being able to modify the content of web sites.
Jesper Johansson discovered that missing sanitising of double-quotes and spaces in URIs passed to external programs may allow an attacker to pass arbitrary arguments to the helper program if the user is tricked into opening a malformed web page.
The Mozilla products in the oldstable distribution (sarge) are no longer supported with security updates.
For the stable distribution (etch) these problems have been fixed in version 22.214.171.124-0etch1.
For the unstable distribution (sid) these problems have been fixed in version 126.96.36.199-1.
We recommend that you upgrade your iceweasel packages.
