Debian Security Advisory 1345-1 - Several remote vulnerabilities have been discovered in Xulrunner, a runtime environment for XUL applications. "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 sanitizing 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.
