Microsoft uncovers critical Windows security hole

Wednesday, 11 February 2004, 9:54 AM EST

Microsoft on Tuesday warned of a serious security vulnerability in all of the current versions of Windows that not only allows an attacker to run code on vulnerable machines, but also enables him to install software and change and delete data.

The vulnerability is covered in Microsoft Security Bulletin MS04-007. The problem, which lies in Microsoft Corp.'s ASN.1 (Abstract Syntax Notation 1) library, is among the most serious flaws yet discovered in Windows, experts said.

Attackers exploiting the weakness essentially would have free reign over compromised machines, which likely would give them access to whatever networks those PCs are on as well.
