An update for compat-openssl11 is now available for openEuler-24.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2025-1287 Final 1.0 1.0 2025-03-14 Initial 2025-03-14 2025-03-14 openEuler SA Tool V1.0 2025-03-14 compat-openssl11 security update An update for compat-openssl11 is now available for openEuler-24.03-LTS-SP1 OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. Security Fix(es): Issue summary: A timing side-channel which could potentially allow recovering the private key exists in the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA signature computations could allow recovering the private key by an attacker. However, measuring the timing would require either local access to the signing application or a very fast network connection with low latency. There is a timing signal of around 300 nanoseconds when the top word of the inverted ECDSA nonce value is zero. This can happen with significant probability only for some of the supported elliptic curves. In particular the NIST P-521 curve is affected. To be able to measure this leak, the attacker process must either be located in the same physical computer or must have a very fast network connection with low latency. For that reason the severity of this vulnerability is Low.(CVE-2024-13176) An update for compat-openssl11 is now available for openEuler-24.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium.
