Adobe Systems Inc, whose software is used by millions of people to read documents sent over the Internet, said on Wednesday some of its programs contain yet-to-be-fixed flaws that make computers vulnerable to attack.
On October 5, Adobe posted a notice on its Web site that said it had unknowingly incorporated vulnerabilities into versions of Adobe Reader and Acrobat software that could allow malicious programs to get on to a PC without the user’s knowledge.
Such malicious software can take control of a machine and steal confidential data, send out tens of thousands of spam e-mails, or infiltrate government computer systems.
Adobe said it believes the flaws only affect computers running Microsoft Corp’s Windows XP operating system and Internet Explorer 7 Web browser. Adobe said it was working to rectify the problem but the fix might not be available until the end of October.
