No Acrobat patch for 3 weeks

A security flaw in Adobe's Acrobat Reader software will not be fixed for three weeks, the company has warned.

Adobe warned that the vulnerability affected Acrobat Reader 9 as well as Acrobat 9 and earlier versions of the software as well.

"Adobe expects to make available an update for Adobe Reader 9 and Acrobat 9 by 11 March, 2009," Adobe said in a statement.

"Updates for Adobe Reader 8 and Acrobat 8 will follow soon after, with Adobe Reader 7 and Acrobat 7 updates to follow," the statement continued.

Security experts warned that the flaw could allow a hacker to take control of your PC.

"The risk is that hackers could deliberately construct a malformed PDF file that would trigger the vulnerability, allowing them to open a backdoor and run malicious code on your computer," said Graham Cluley of security firm Sophos.
