Subject: libssh 0.6.5 has been released to address CVE-2015-3146
To: <libssh at libssh.org>

ibssh versions 0.5.1 and above have a logical error in the handling of a
SSH_MSG_NEWKEYS and SSH_MSG_KEXDH_REPLY package. A detected error did not
the session into the error state correctly and further processed the packet
which leads to a null pointer dereference. This is the packet after the
initial key exchange and doesn’t require authentication.

This could be used for a Denial of Service (DoS) attack.

The bug was found and reported by Mariusz Ziulek from the Open Web
Security Project (OWASP).
