Security Fix(es): A security vulnerability has been detected in libssh2 up to 1.11.1. The impacted element is the function userauth_password of the file src/userauth.c. Such manipulation of the argument username_len/password_len leads to integer overflow. The attack may be launched remotely. The name of the patch is 256d04b60d80bf1190e96b0ad1e91b2174d744b1. A patch should be applied to remediate this issue.(CVE-2026-7598) An update for libssh2 is now available for openEuler-22.03-LTS-SP4,openEuler-24.03-LTS,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP3,openEuler-20.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high.
