DESCRIPTION:
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. Other versions may
also be affected.

SOLUTION:
Fixed in the GIT repository.
