ymantec Corp.'s leading antivirus software, which protects some of the world's largest corporations and U.S. government agencies, suffers from a flaw that lets hackers seize control of computers to steal sensitive data, delete files or implant malicious programs, researchers said Thursday.
Symantec said it was investigating the issue but could not immediately corroborate the vulnerability. If confirmed, the threat to computer users would be severe because the security software is so widely used and because no action is required by victims using the latest versions of Symantec Antivirus to suffer a crippling attack over the Internet.
Researchers from eEye Digital Security Inc. of Aliso Viejo, California, discovered the vulnerability and provided evidence to Symantec engineers this week, said eEye's chief hacking officer, Marc Maiffret. He demonstrated the attack for The Associated Press.
eEye said it appeared consumer versions of Symantec's Norton Antivirus software -- sold at retail outlets around the country -- were not vulnerable to the flaw, though consumers who are provided Symantec's corporate edition antivirus software by their employers for use at home may be affected.
Maiffret published a note about the company's discovery on its Web site but pledged not to reveal details publicly that would help hackers attack Internet users until after Symantec repairs its antivirus software. eEye said it intends to describe the problem in detail privately for some of its largest customers.
"People shouldn't panic," Maiffret said. "There shouldn't be any exploits until a patch is produced."
