{"id":"OESA-2025-1174","summary":"gnutls security update","details":"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.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.(CVE-2024-12243)","modified":"2026-08-18T01:18:47.746471619Z","published":"2025-02-21T11:08:16Z","upstream":["CVE-2024-12243"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2025-1174"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-12243"}],"affected":[{"package":{"name":"gnutls","ecosystem":"openEuler:22.03-LTS-SP3","purl":"pkg:rpm/openEuler/gnutls&distro=openEuler-22.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.2-15.oe2203sp3"}]}],"ecosystem_specific":{"noarch":["gnutls-help-3.7.2-15.oe2203sp3.noarch.rpm"],"src":["gnutls-3.7.2-15.oe2203sp3.src.rpm"],"x86_64":["gnutls-3.7.2-15.oe2203sp3.x86_64.rpm","gnutls-debuginfo-3.7.2-15.oe2203sp3.x86_64.rpm","gnutls-debugsource-3.7.2-15.oe2203sp3.x86_64.rpm","gnutls-devel-3.7.2-15.oe2203sp3.x86_64.rpm","gnutls-utils-3.7.2-15.oe2203sp3.x86_64.rpm"],"aarch64":["gnutls-3.7.2-15.oe2203sp3.aarch64.rpm","gnutls-debuginfo-3.7.2-15.oe2203sp3.aarch64.rpm","gnutls-debugsource-3.7.2-15.oe2203sp3.aarch64.rpm","gnutls-devel-3.7.2-15.oe2203sp3.aarch64.rpm","gnutls-utils-3.7.2-15.oe2203sp3.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2025-1174.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
