Mandriva Linux Security Advisory : libssh2 (MDVSA-2015:148-1)

Medium Nessus Plugin ID 82401


The remote Mandriva Linux host is missing one or more security updates.


Updated libssh2 packages fix security vulnerability :

Mariusz Ziulek reported that libssh2, a SSH2 client-side library, was reading and using the SSH_MSG_KEXINIT packet without doing sufficient range checks when negotiating a new SSH session with a remote server.
A malicious attacker could man in the middle a real server and cause a client using the libssh2 library to crash (denial of service) or otherwise read and use unintended memory areas in this process (CVE-2015-1782).

Update :

Packages were misssing for Mandriva Business Server 1 with the MDVSA-2015:148 advisory which are now being provided.


Update the affected lib64ssh2-devel and / or lib64ssh2_1 packages.
