Adobe warned of reports of an attack exploiting a hole in Reader and Acrobat.

In a statement the outfit said that it had received reports of a vulnerability in Adobe Reader and Acrobat 9.2 and earlier versions being exploited. The outfit said that it was currently investigating this problem and assessing the risk to its customers.

An Adobe spokeswoman said the problem had been reported by three different security vendors, although she was not providing more details. It has been a fairly tough year for Adobe on the security front. Last week, Adobe released a critical update affecting Flash Player and Adobe AIR. But Adobe's software has been blighted with security problems as hackers target its products to launch Trojans.

Yesterday Mac users were moaning that they were having problems installing an update from October that resolved a critical vulnerability in Adobe Reader and Acrobat 9.1.3 that had reportedly been exploited in the wild.
