{"id":"OESA-2026-1417","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 the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks.(CVE-2025-9820)","modified":"2026-08-18T01:19:40.185549600Z","published":"2026-02-13T11:10:26Z","upstream":["CVE-2025-9820"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1417"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-9820"}],"affected":[{"package":{"name":"gnutls","ecosystem":"openEuler:22.03-LTS-SP4","purl":"pkg:rpm/openEuler/gnutls&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.2-19.oe2203sp4"}]}],"ecosystem_specific":{"x86_64":["gnutls-3.7.2-19.oe2203sp4.x86_64.rpm","gnutls-debuginfo-3.7.2-19.oe2203sp4.x86_64.rpm","gnutls-debugsource-3.7.2-19.oe2203sp4.x86_64.rpm","gnutls-devel-3.7.2-19.oe2203sp4.x86_64.rpm","gnutls-utils-3.7.2-19.oe2203sp4.x86_64.rpm"],"aarch64":["gnutls-3.7.2-19.oe2203sp4.aarch64.rpm","gnutls-debuginfo-3.7.2-19.oe2203sp4.aarch64.rpm","gnutls-debugsource-3.7.2-19.oe2203sp4.aarch64.rpm","gnutls-devel-3.7.2-19.oe2203sp4.aarch64.rpm","gnutls-utils-3.7.2-19.oe2203sp4.aarch64.rpm"],"noarch":["gnutls-help-3.7.2-19.oe2203sp4.noarch.rpm"],"src":["gnutls-3.7.2-19.oe2203sp4.src.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-1417.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
