Fortinet Discovers Foxit PDF Compressor DLL Preloading Vulnerability
Fortinet's FortiGuard Labs has discovered a DLL preloading vulnerability in Foxit PDF Compressor.
The Foxit PDF Compressor is the professional solution for process-oriented document conversion and compression. The flexibly scalable solution is designed for the processing of small to very high data volumes.
Foxit PDF Compressor is susceptible to a DLL preloading vulnerability. The issue occurs when the application looks to load a DLL for execution and an attacker provides a malicious DLL to use instead. The application generally follows a specific search path to locate the DLL. The vulnerability can be exploited by a simple file write (or potentially an over-write) which results in a foreign DLL running under the context of the application.
Users should apply the solution provided by Foxit.
Fortinet reported the vulnerability to Foxit on June 16, 2017.
Foxit released patch for it on July 26, 2017.
