PCs falling victim to Windows flaws

One of the problems affects the Microsoft Color Management Module, a component of Windows that handles colors. The other relates to the JView Profiler, part of Microsoft's Java Virtual Machine. The vulnerabilities could be used to commandeer a PC, Microsoft said.

"Attackers are already using the JView Profiler flaw to download and install Trojan horses on victims' machines," said Dan Hubbard, senior director at Websense Security Labs. The Trojan horses would let the miscreants remotely control the hijacked PCs and make it part of a network of such computers known as a botnet, an increasing cyberthreat.
