Windows DLL Load Hijacking Exploits Go Wild

Gregg Keizer writes on ComputerWorld:

Less than 24 hours after Microsoft said it couldn't patch Windows to fix a systemic problem, attack code appeared Tuesday to exploit the company's software.

Also on Tuesday, a security firm that's been researching the issue for the past nine months said 41 of Microsoft's own programs can be remotely exploited using DLL load hijacking, and it named two of them.

On Monday, Microsoft confirmed reports of unpatched -- or zero-day -- vulnerabilities in a large number of Windows programs, then published a tool it said would block known attacks. At the same time, the company said it would not patch Windows because doing so would cripple existing applications.

Microsoft also declined to reveal whether any of its own applications contain bugs that attackers could exploit, saying only that it is investigating.
