An update for libssh is now available for openEuler-22.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1123 Final 1.0 1.0 2024-02-02 Initial 2024-02-02 2024-02-02 openEuler SA Tool V1.0 2024-02-02 libssh security update An update for libssh is now available for openEuler-22.03-LTS-SP2. The ssh library was designed to be used by programmers needing a working SSH implementation by the mean of a library. The complete control of the client is made by the programmer. With libssh, you can remotely execute programs, transfer files, use a secure and transparent tunnel for your remote programs. With its Secure FTP implementation, you can play with remote files easily, without third-party programs others than libcrypto (from openssl). Security Fix(es): A flaw was found in libssh. By utilizing the ProxyCommand or ProxyJump feature, users can exploit unchecked hostname syntax on the client. This issue may allow an attacker to inject malicious code into the command of the features mentioned through the hostname parameter.(CVE-2023-6004) An update for libssh is now available for openEuler-22.03-LTS-SP2. openEuler Security has rated this update as having a security impact of medium.
