Summary

openssh vulnerability

Details

USN-6242-1 fixed a vulnerability in OpenSSH. This update provides the corresponding update for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 18.04 LTS.

It was discovered that OpenSSH incorrectly handled loading certain PKCS#11 providers. If a user forwarded their ssh-agent to an untrusted system, a remote attacker could possibly use this issue to load arbitrary libraries from the user's system and execute arbitrary code.
