SUSE CVE-2026-9547

When a libcurl-based application performs transfers via SCP:// or SFTP:// and utilizes the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This vulnerability occurs when a server presents a host key type that does not match the specific key type already recorded for th...

SUSE CVE-2026-12064

When a user invokes curl using a schemeless URL combined with --proto-default sftp or scp, a disconnect occurs between the tool layer and libcurl. The tool layer incorrectly infers the URL scheme, which erroneously bypasses the initialization of critical SSH security options like...

OpenSSH < 10.4 Multiple Vulnerabilities

The version of OpenSSH installed on the remote host is prior to 10.4. It is, therefore, affected by multiple vulnerabilities, including: - ssh in OpenSSH before 10.4 can have a use-after-free when a server changes its host key during a key re-exchange. This outcome occurs only on the client side...

openssh: OpenSSH: Use-after-free vulnerability during host key re-exchange on the client side

A flaw was found in OpenSSH. A remote attacker could exploit a use-after-free vulnerability on the client side when a server changes its host key during a key re-exchange. This could lead to high impact on confidentiality and integrity, and low impact on availability...
