Foxit Reader 2.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PDF file with (1) a malformed ExtGState resource containing a /Font resource, or (2) an XObject resource with a Rotate setting, which triggers memory corruption. NOTE: this is probably a different vulnerability than CVE-2007-2186.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
