The Acrobat web control in Adobe Acrobat and Acrobat Reader 7.0 and earlier, when used with Internet Explorer, allows remote attackers to determine the existence of arbitrary files via the LoadFile ActiveX method.

Buffer overflow in the ActiveX component (pdf.ocx) for Adobe Acrobat 5.0.5 and Acrobat Reader, and possibly other versions, allows remote attackers to execute arbitrary code via a URI for a PDF file with a null terminator (%00) followed by a long string.

Stack-based buffer overflow in the OutputDebugString function for Adobe Acrobat Reader 5.1 allows remote attackers to execute arbitrary code via a PDF document with XML Forms Data Format (XFDF) data.
