Multiple vulnerabilities has been identified in Mozilla products, which could be exploited by remote attackers to compromise a vulnerable system.
The first issue is caused by an error in the internal CSSValue array data structure when processing an overly large number of references to a common CSS object, which could allow attackers to execute arbitrary code by tricking a user into visiting a malicious and specially crafted web page.
A second vulnerability is caused by an error when passing a command-line URI with pipe symbols to Firefox, which could be exploited in combination with an input validation error within the handling of XUL based error pages to inject script into a chrome document and execute arbitrary code.
