This afternoon, Adobe received reports of a vulnerability in Adobe Reader and Acrobat 9.2 and earlier versions being exploited in the wild (CVE-2009-4324). 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. Please continue monitoring the Adobe PSIRT blog for the latest information.
As of tonight the Adobe PSIRT blog had few details to report. Computerworld reports they have searched security mailing lists and sites, including Bugtraq, Full Disclosure and milw0rm.com but turned up no reports of exploits in the wild.
An Adobe representative described why, saying, "The reports came to PSIRT directly from partners in the security community," Adobe's Wiebke Lips said. "As of this moment, I have not seen any public reports aside from the Adobe PSIRT blog post that just went live."
