An update for gnutls is now available for openEuler-20.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1046 Final 1.0 1.0 2021-03-05 Initial 2021-03-05 2021-03-05 openEuler SA Tool V1.0 2021-03-05 gnutls security update An update for gnutls is now available for openEuler-20.03-LTS. 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. Security Fix(es): An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.(CVE-2020-24659) An update for gnutls is now available for openEuler-20.03-LTS. openEuler Security has rated this update as having a security impact of high.
