NOTE: Other versions may also be affected.
Rating: Highly critical
Impact: System compromise
"Those wishing to view PDF files on their Windows PC's now have a choice when it comes to Viewing PDF files - the PDF-XChange Viewer is smaller, faster and more feature rich than the Adobe Reader which has until now been the Reader of choice for PDF files - we think that's about to change!".
Secunia Research has discovered a vulnerability in PDF-XChange Viewer, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an input validation error in PDFXCview.exe when parsing certain content and can be exploited to corrupt memory via a specially crafted PDF file.
Successful exploitation allows execution of arbitrary code when a user views a malicious PDF document.
NOTE: The vulnerable code is e.g. also present in the bundled PDF-XChange shell extension (XCShInfo.dll), which is installed by default. This vector allows exploitation as soon as a user e.g. selects a malicious PDF file or hovers the mouse pointer over it.
Update to version 2.044.
