Unpatched Vulnerability 1: Apple QuickTime version 126.96.36.199
The Firefox update above resolves the issue raised by Petko D. Petkov, which details how a simple quicktime file can execute arbitrary code from the said browser. In his report, a QTL file which serves as an encapsulation for loading a real media file, can contain a qtnext field which may have parameters in execution of code thru Firefox. So, users can just avoid the link from a Web site if the file in the link has an extension in .QTL, right? Wrong. The file can be renamed as .MP3 or .MOV (or any file extension supported by QT) and the file would still be processed as a QTL file. The exploit has been verified to work on Firefox 188.8.131.52 (thus necessitating the update) and the latest QuickTime version 184.108.40.206 (still unpatched).

Unpatched Vulnerability 2: Microsoft MFC42 and MFC71 Heap Overflow Allows RCE
Jonathan Sarba from GoodFellas Security Research Team recently disclosed the Findfile Class implementation in the MFC42 and MFC71 library lacks checking of the buffer, allowing a heap overflow to execute arbitrary code. Any application using CFileFind::FindFile from MFC42.DLL and MFC71.dll may be susceptible to this attack. If you remember, a previous MFC vulnerability was patched last June. Considering the possibilities, could there be an upcoming Month of MFC Bugs?
