An update for libssh is now available for openEuler-20.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2025-1707 Final 1.0 1.0 2025-07-04 Initial 2025-07-04 2025-07-04 openEuler SA Tool V1.0 2025-07-04 libssh security update An update for libssh is now available for openEuler-20.03-LTS-SP4 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 the libssh library. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.(CVE-2025-5318) An update for libssh is now available for openEuler-20.03-LTS-SP4. openEuler Security has rated this update as having a security impact of medium.
