{"id":"OESA-2026-4213","summary":"botan2 security update","details":"Botan is a BSD-licensed crypto library written in C++. It provides a wide variety of basic cryptographic algorithms, X.509 certificates and CRLs, PKCS \\#10 certificate requests, a filter/pipe message processing system, and a wide variety of other features, all written in portable C++. The API reference, tutorial, and examples may help impart the flavor of the library. This is the current stable release branch 2.x of Botan.\r\n\r\nSecurity Fix(es):\n\nBotan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which prohibits indefinite length encodings. This vulnerability is fixed in 3.12.0.(CVE-2026-44378)","modified":"2026-10-01T02:00:13.910557211Z","published":"2026-09-30T13:47:40Z","upstream":["CVE-2026-44378"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4213"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44378"}],"affected":[{"package":{"name":"botan2","ecosystem":"openEuler:24.03-LTS-SP4","purl":"pkg:rpm/openEuler/botan2&distro=openEuler-24.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.19.3-7.oe2403sp4"}]}],"ecosystem_specific":{"src":["botan2-2.19.3-7.oe2403sp4.src.rpm"],"x86_64":["botan2-2.19.3-7.oe2403sp4.x86_64.rpm","botan2-debuginfo-2.19.3-7.oe2403sp4.x86_64.rpm","botan2-debugsource-2.19.3-7.oe2403sp4.x86_64.rpm","botan2-devel-2.19.3-7.oe2403sp4.x86_64.rpm","python3-botan2-2.19.3-7.oe2403sp4.x86_64.rpm"],"aarch64":["botan2-2.19.3-7.oe2403sp4.aarch64.rpm","botan2-debuginfo-2.19.3-7.oe2403sp4.aarch64.rpm","botan2-debugsource-2.19.3-7.oe2403sp4.aarch64.rpm","botan2-devel-2.19.3-7.oe2403sp4.aarch64.rpm","python3-botan2-2.19.3-7.oe2403sp4.aarch64.rpm"],"noarch":["botan2-doc-2.19.3-7.oe2403sp4.noarch.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4213.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:H"}]}
