An update for openssh is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1063 Final 1.0 1.0 2023-02-10 Initial 2023-02-10 2023-02-10 openEuler SA Tool V1.0 2023-02-10 openssh security update An update for openssh is now available for openEuler-22.03-LTS. 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): OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling. This is fixed in OpenSSH 9.2. The double free can be triggered by an unauthenticated attacker in the default configuration. One third-party report states "remote code execution is theoretically possible."(CVE-2023-25136) An update for openssh is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of medium.
