Maurycy Prodeus has reported a vulnerability in Mozilla, which potentially can be exploited by malicious people to compromise a user's system.

 

The vulnerability is caused due to a boundary error in the "MSG_UnEscapeSearchUrl()" function in "nsNNTPProtocol.cpp" when processing NNTP URIs. This can be exploited via e.g. a malicious web site to cause a heap-based buffer overflow when referencing a specially crafted, overly long "news://" URI.

 

Successful exploitation may allow execution of arbitrary code.

 

The vulnerability has been reported in version 1.7.3 and prior.

 

Solution:

Update to version 1.7.5.

 

Please note: This affects Mozilla not Firefox as far as I can tell.
