CNET reports attacks are exploiting a security hole in Adobe's Acrobat and Reader 9.2:
"This afternoon, Adobe received reports of a vulnerability in Adobe Reader and Acrobat 9.2 and earlier versions being exploited in the wild," the company said in an advisory on its Security Incident Response Team blog. "We are currently investigating this issue and assessing the risk to our customers. We will provide an update as soon as we have more information."
Three different security vendor partners reported the alleged exploit to the company on Monday afternoon, said Adobe spokeswoman Wiebke Lips. She said she could not provide more details.
