Detailsinfo

A vulnerability classified as problematic has been found in Mozilla Firefox 1.5/1.5.0.1/1.5.0.2/1.5.0.3/1.5.0.4 (Web Browser). This affects some unknown functionality of the file Function.prototype.call of the component Proxy AutoConfig. The manipulation with an unknown input leads to a integer coercion vulnerability. CWE is classifying the issue as CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Mozilla Firefox before 1.5.0.5 and SeaMonkey before 1.0.3 allows remote Proxy AutoConfig (PAC) servers to execute code with elevated privileges via a PAC script that sets the FindProxyForURL function to an eval method on a privileged object.

The weakness was presented 07/25/2006 by Benjamin Smedberg (moz_bug_r_a4) with TippingPoint and the Zero Day Initiative as MFSA2006-52 as confirmed advisory (Website). It is possible to read the advisory at mozilla.org. This vulnerability is uniquely identified as CVE-2006-3808 since 07/24/2006. It is possible to initiate the attack remotely.
