Security company pokes hole in WinXP SP2

Patch is available, but some experts advise against installing it.

"Russian security company Positive Technologies has released a patch to a security hole it said it discovered in Microsoft's Windows XP Service Pack 2 last year.

"We found two small flaws that a programmer could use to go around the SP2 mechanism Data Execution Protection [DEP]," says Positive Technologies Chief Technology Officer Yury Maximov.

As Microsoft explains on its Web site, DEP is a set of hardware and software technologies that perform additional checks on memory to help prevent malicious code from running on a system. According to Maximov, Positive Technologies informed the Redmond, Washington, software maker on December 22 about a problem with DEP and was told to wait for a response from the company.

"It has been over one month and we have not heard from Microsoft, so we decided to issue our own patch," Maximov says. "We understand that Microsoft wants to protect its product, but we feel it is more important for people to know about the problem and to know there is a tool to protect them."

Maximov adds that it was his understanding that hacker groups were already working on ways to exploit the holes in DEP so as to insert rogue code into a PC's memory.

Representatives from Microsoft could not immediately be reached for comment."
