Description

A vulnerability has been discovered in Mozilla Firefox, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the application loading libraries (e.g. dwmapi.dll) in an insecure manner. This can be exploited to load arbitrary libraries by tricking a user into e.g. opening an HTML file located on a remote WebDAV or SMB share.

Successful exploitation allows execution of arbitrary code.

Solution
Update to version 3.6.9 or 3.5.12.

Provided and/or discovered by
* Glafkos Charalambous
* The vendor also credits Haifei Li of FortiGuard Labs and Acros Security.

According to https://bugzilla.mozilla.org/show_bug.cgi?id=59157... , Mozilla's reference for this is https://bugzilla.mozilla.org/show_bug.cgi?id=57959... , although that bug is still locked.

It seems to have been fixed in the source code, so I guess that 3.6.9 will fix this (a release candidate for 3.6.9 just came out, and it's scheduled for release on September 7th).

Hello @petereigler ,

This thread in this "vulnerabilities" sub-forum is for discussing the technical details of the vulnerability described in the Secunia Advisory 41095 (see link just above the thread header/title.

Your question is more general concerning your system's security and it would be best reposted by creating your own thread in say the "Program" sub-forum ; for details see the column on the upper left hand side of this webpage .

Take care

Anthony

Version 3.6.9 still shows up as vulnerable to this exploit. I thought this version has fixed this problem. Or maybe the database has been been updated until you have confirmed this.
