Microsoft announced a software update to close a critical hole in a common service used by WIndows XP systems to share local printers. Experts say the hole, which was discovered by researchers at Kaspersky Lab, was one of four previously unknown attacks used in the recent Stuxnet outbreak. The hole, if left unpatched, could allow an attacker to connect to the print spooler service on a compromised Windows XP system without authenticating first. Microsoft announced the security fix as part of its monthly Patch Tuesday update.
