A malicious PDF document that exploits bugs in Adobe Systems Inc.'s Reader and Acrobat software is on the loose, Symantec Corp. said today, just hours after Adobe patched the programs.
"This mass mailing of exploit files may be an attempt to leverage the exposure window between patch release and widespread adoption of the fix," said Symantec in a warning to customers of its DeepSight threat intelligence network.
The rogue PDF document is attached to spammed e-mail, and arrives with a filename such as YOUR_BILL.pdf or INVOICE.pdf, said Symantec. It exploits the "mailto:" protocol vulnerability disclosed more than a month ago by U.K.-based researcher Petko Petkov.
