OESA-2025-1440 (CVE-2025-26465)

Vulnerability from osv_openeuler – Published: 2025-04-18 11:08 – Updated: 2026-08-06 11:08 – Source website

Summary

openssh security update

Details

OpenSSH is the premier connectivity tool for remote login with the SSH protocol. \ It encrypts all traffic to eliminate eavesdropping, connection hijacking, and \ other attacks. In addition, OpenSSH provides a large suite of secure tunneling \ capabilities, several authentication methods, and sophisticated configuration options.

Security Fix(es):

A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high.(CVE-2025-26465)

In sshd in OpenSSH before 10.0, the DisableForwarding directive does not adhere to the documentation stating that it disables X11 and agent forwarding.(CVE-2025-32728)

Severity

6.8 (Medium)

OESA-2025-1664 (CVE-2025-32728)

Vulnerability from osv_openeuler – Published: 2025-06-20 11:08 – Updated: 2026-08-06 11:08 – Source website

Summary

openssh security update

Details

Security Fix(es):

OpenSSH (OpenBSD Secure Shell) is a set of connection tools for secure access to remote computers in the Canadian OpenBSD program group. This tool is an open source implementation of the SSH protocol, supports encryption of all transmissions, and can effectively prevent eavesdropping, connection hijacking, and other network-level attacks. OpenSSH (OpenBSD Secure Shell) versions before 10.0 have a security vulnerability that originated from the DisableForwarding directive that does not correctly disable X11 and proxy forwarding.(CVE-2025-32728)

Severity

3.8 (Low)
