RockyLinux 8 : openssh (RLSA-2026:69266)
The remote RockyLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:69266 advisory. openssh: OpenSSH: sftp client allows attacker to control downloaded file location CVE-2026-59995 openssh: OpenSSH sshd: Security bypass due to incorrect...
openssh: OpenSSH sshd: Security bypass due to incorrect handling of forwarding and tunneling options
A flaw was found in sshd, the OpenSSH server daemon. When DisableForwarding=yes is configured to prevent network traffic forwarding, it incorrectly fails to take precedence over PermitTunnel=yes. This allows a remote attacker to bypass intended security restrictions and establish a tunnel,...
openssh: OpenSSH: Tunnel forwarding restriction bypass
A flaw was found in OpenSSH's sshd component. The restrict keyword, designed to limit tunnel forwarding within the authorizedkeys file, was not correctly enforced for tunnel forwarding. This issue could allow a local attacker to bypass intended security restrictions, potentially leading to...
openssh: OpenSSH: ssh-agent allows remote execution of local operations
A flaw was found in OpenSSH's ssh-agent component. A misinteraction between agent locking and the [email protected] extension allows operations intended for local execution to be performed remotely. This could enable a remote attacker to add PKCS11 tokens or utilize keys with destination...
openssh: OpenSSH: sftp client allows attacker to control downloaded file location
A flaw was found in OpenSSH. The sftp client, when used to download files from a malicious server with the 'sftp server:/path .' command, does not properly restrict where those files are saved. This allows an attacker to control the download location, potentially overwriting existing files or...

openssh: OpenSSH: Information disclosure and data corruption via use-after-free in ssh client
A flaw was found in OpenSSH. A use-after-free vulnerability exists in the ssh client when handling concurrent remote-forwarding operations. This can occur if a remote forwarding is added via the local session multiplexing socket while a remote forwarding open request is pending with the server. A...
