Luigi Auriemma has discovered a vulnerability in SumatraPDF, which can be exploited by malicious people to potentially compromise a user's system.

The vulnerability is caused due to the "fz_crash_abort()" function trying to write a NULL byte to an address that can be controlled by the attacker. This can be exploited to corrupt memory by e.g. tricking a user into opening a specially crafted PDF file.

The vulnerability is confirmed in version 1.9. Prior versions may also be affected.

Solution
Apply fix from the GIT repository, or upgrade to version 2.0 or later.
