The code in src/sftpserver.c did not verify the validity of certain pointers and expected them to be valid. A NULL pointer dereference could have been occured that typically causes a crash and thus a denial-of-service.



For Debian 8 jessie, these problems have been fixed in version 0.6.3-4+deb8u5.

We recommend that you upgrade your libssh packages.
