PDF is closely associated with products such as Adobe Reader and Acrobat, but Arkin pointed out that the file format has been an open ISO Standard since 2008.
"Anyone can develop and distribute software to create and view PDF documents. This means that not all PDF-related vulnerabilities are automatically Adobe vulnerabilities," he said in blog post.
According to Arkin, the iPhone jailbreak PDF vulnerability appears to be in the implementation of the PDF viewing technology and not with the PDF specification.
Initial reports that the latest iPhone jailbreak crashes Adobe Reader have since been retracted, said Arkin.
"All of our analysis to date indicates that the vulnerability used in the iPhone jailbreak does not impact Adobe Reader or Acrobat," he said.
