Acrobat products have historically opened a PDF as long as the %PDF-header started anywhere within the first 1024 bytes of the file. No checks were performed on the extraneous bytes before the %PDF-header. However, the 10.1.5 and 11.0.01 updates improve security by enforcing stricter parsing of the PDF-header.
If you manage or administer software that automatically generates PDFs, modify the way the PDF is produced. Make sure that no extraneous bytes appear before %PDF at the head of the file.
If you are a customer or an enterprise IT professional, you can disable the header validation on machines by setting the appropriate preference. You can set this preference per user in HKCU or at the machine level for all users in HKLM. You can use a similar method on Mac OS by modifying the same plist preference.
