Windows DLL bug hits dozens of apps2010-08-25 09:34 by DanielaTags: Windows, security
A flaw in the way Windows handles DLL (dynamic-link library) and related files likely affects hundreds of applications and has already been used in malicious attacks in the wild, a security researcher said on Tuesday. Microsoft acknowledged in an advisory on Monday a type of attack mechanism known as DLL preloading, or binary planting and said that while it is not new it does have a new remote-attack vector. Malicious code can now be planted on a network share instead of just on a local system, making it much easier to attack vulnerable systems by duping people into clicking on malicious Web links or opening malicious documents. Security firm Acros disclosed the issue last week after finding that it affects iTunes, and Rapid7 Chief Technology Officer HD Moore published additional information about it this week here and here. Moore, creator of the Metasploit database and framework, also released a tool to test whether applications are vulnerable. Now, the Exploit-db.com exploit database is getting flooded with submissions of applications that people say are vulnerable, including Windows Live Mail, Windows Movie Maker, Microsoft PowerPoint 2010, Office 2007, and non-Microsoft applications like Firefox 3.6.8, Foxit Reader, Wireshark and uTorrent, said Mati Aharoni, founder of security firm Offensive Security, which runs the exploit database.
