Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the conversion of TIFF files into PDF format. By providing a malformed TIFF, an attacker can cause Foxit Reader to read a VTable from an invalid location. This could allow an attacker to execute arbitrary code under the context of the Reader process.
