An update for gnutls is now available for openEuler-20.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1092 Final 1.0 1.0 2024-01-26 Initial 2024-01-26 2024-01-26 openEuler SA Tool V1.0 2024-01-26 gnutls security update An update for gnutls is now available for openEuler-20.03-LTS-SP4. GnuTLS is a secure communications library implementing the SSL, TLS and DTLS protocols and technologies around them. It provides a simple C language application programming interface (API) to access the secure communications protocols as well as APIs to parse and write X.509, PKCS #12, and other required structures. The project strives to provide a secure communications back-end, simple to use and integrated with the rest of the base Linux libraries. A back-end designed to work and be secure out of the box, keeping the complexity of TLS and PKI out of application code. Security Fix(es): A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.(CVE-2024-0553) An update for gnutls is now available for openEuler-20.03-LTS-SP4. openEuler Security has rated this update as having a security impact of medium.
