Description

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. Original advisory details: 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. Update Instructions: Run `sudo pro fix USN-6242-2` to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: openssh-client - 1:7.2p2-4ubuntu2.10+esm3 ssh-askpass-gnome - 1:7.2p2-4ubuntu2.10+esm3 openssh-server - 1:7.2p2-4ubuntu2.10+esm3 openssh-client-ssh1 - 1:7.2p2-4ubuntu2.10+esm3 ssh - 1:7.2p2-4ubuntu2.10+esm3 ssh-krb5 - 1:7.2p2-4ubuntu2.10+esm3 openssh-sftp-server - 1:7.2p2-4ubuntu2.10+esm3 Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro
