CVE-2015-0803

Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 37.0

Description The issue is related to the HTMLSourceElement::AfterSetAttr function, which does not properly constrain the original data type of a casted value during the setting of a SOURCE element's attributes. This allows a remote attacker to execute arbitrary code or cause a denial of service (use-after-free) via a crafted HTML document.

Recommendations For versions prior to 37.0, update to version 37.0 or later to resolve the issue. As a temporary workaround, consider restricting access to HTML documents from untrusted sources to minimize the risk of exploitation.
