Two vulnerabilities have been discovered in Foxit Reader, which can be exploited by malicious people to compromise a user's system.
1) A boundary error in the FoxitReaderOCX ActiveX control when processing the "OpenFile()" method can be exploited to cause a heap-based buffer overflow via an overly long string passed in the "strFilePath" parameter.
2) The application loads libraries (e.g. dwmapi.dll and dwrite.dll) in an insecure manner and can be exploited to load arbitrary libraries by tricking a user into e.g. opening a PDF file located on a remote WebDAV or SMB share.
Successful exploitation of these vulnerabilities allows execution of arbitrary code.
The vulnerabilities are confirmed in version 5.0.1.0523. Other versions may also be affected.
Solution: Update to version 5.0.2.0718.
Provided and/or discovered by: 1) Originally reported by SarBoT511 and D3V!L FUCKER in version 220.127.116.115, but the control was not marked "safe for scripting". Fixed in version 18.104.22.1680 at the same time as the control was marked "safe for scripting".
Discovery of regression in the "safe for scripting" control in version 5.0.1.0523 by Secunia Research.
2) Jose Hernandez, Solutionary Engineering Research Team (SERT).
