Foxit Reader "util.printf()" Buffer Overflow

Recommended Posts


Secunia (secunia.com/advisories/29941)



Highly critical



Secunia Research has discovered a vulnerability in Foxit Reader, which can be exploited by malicious people to compromise a user's system.


The vulnerability is caused due to a boundary error when parsing format strings containing a floating point specifier in the "util.printf()" JavaScript function. This can be exploited to cause a stack-based buffer overflow via a specially crafted PDF file.


Successful exploitation allows execution of arbitrary code.


The vulnerability is confirmed in version 2.3 build 2825. Other versions may also be affected.



The vulnerability is fixed in upcoming version 2.3 build 2912.

The updated version taking care of this problem has now been released (build number seems to have been changed though). :starwars:
