Notes

Title of the patch
Security update for openssh
Description of the patch
This update for openssh fixes the following issues: Security vulnerabilities addressed: - CVE-2019-6109: Fixed an character encoding issue in the progress display of the scp client that could be used to manipulate client output, allowing for spoofing during file transfers (bsc#1121816). - CVE-2019-6111: Properly validate object names received by the scp client to prevent arbitrary file overwrites when interacting with a malicious SSH server (bsc#1121821). Other issues fixed: - Fixed two race conditions in sshd relating to SIGHUP (bsc#1119183). - Returned proper reason for port forwarding failures (bsc#1090671). - Fixed SSHD termination of multichannel sessions with non-root users (bsc#1115550).
