Raw Blame History

Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=742
We have identified the following memory corruption vulnerability in Foxit PDF Reader (version 1.0.1.0925 for Linux 64-bit), when started with a specially crafted PDF file in the following way:
$ DISPLAY=:1 FoxitReader /path/to/poc/file.pdf
The DISPLAY=:1 environment variable is set due to the fact that we are testing the application with a virtual X server (Xvfb), but the issue should be equally reproducible with the program started with standard display settings, too.
An example excerpt from the crash log is as follows:
--- cut ---
Program received signal SIGSEGV, Segmentation fault.
