NVD Description

Note: Versions mentioned in the description apply only to the upstream filezilla package and not the filezilla package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

Heap-based buffer underflow in the modmul function in sshbn.c in PuTTY before 0.63 allows remote SSH servers to cause a denial of service (crash) and possibly trigger memory corruption or code execution via a crafted DSA signature, which is not properly handled when performing certain bit-shifting operations during modular multiplication.
