Description OSIDB Bzimport 2026-10-06 21:42:14 UTC 
In sshd in OpenSSH through 10.6, in certain environments such as QNX 6 and SCO OpenServer 5, sshd-session can unexpectedly have root privileges. This is related to the GatewayPorts and StreamLocalForwarding configuration options, and lack of support for file-descriptor passing and unprivileged allocation of PTY devices.
