========================================================================== Ubuntu Security Notice USN-8514-1 July 06, 2026
openssh vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary:
OpenSSH could be made to overwrite files as the administrator.
Software Description:
- openssh: secure shell (SSH) for secure access to remote machines
Details:
It was discovered that OpenSSH incorrectly handled file permissions when
downloading files as root using the legacy scp protocol without the
preserve-mode option. An attacker could use this to install setuid or setgid
files on a system, possibly leading to privilege escalation.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.04 LTS
openssh-client 1:7.2p2-4ubuntu2.10+esm8
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.
