{"id":"OESA-2026-4660","summary":"tftp security update","details":"TFTP which is the abbreviation of Trivial File Fransfer Protocol enables users to transfer files between local host and remote machine. This package tftp is a client implementing TFTP.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in tftp-hpa. When the `in.tftpd` remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the `genmatchstring()` function. This leads to out-of-bounds read/write operations. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted request, causing the daemon to crash and resulting in a denial of service.(CVE-2026-85234)","modified":"2026-11-04T14:00:04.428521798Z","published":"2026-11-04T13:54:11Z","upstream":["CVE-2026-85234"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4660"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85234"}],"affected":[{"package":{"name":"tftp","ecosystem":"openEuler:24.03-LTS-SP3","purl":"pkg:rpm/openEuler/tftp&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.2-33.oe2403sp3"}]}],"ecosystem_specific":{"src":["tftp-5.2-33.oe2403sp3.src.rpm"],"x86_64":["tftp-5.2-33.oe2403sp3.x86_64.rpm","tftp-debuginfo-5.2-33.oe2403sp3.x86_64.rpm","tftp-debugsource-5.2-33.oe2403sp3.x86_64.rpm","tftp-server-5.2-33.oe2403sp3.x86_64.rpm"],"aarch64":["tftp-5.2-33.oe2403sp3.aarch64.rpm","tftp-debuginfo-5.2-33.oe2403sp3.aarch64.rpm","tftp-debugsource-5.2-33.oe2403sp3.aarch64.rpm","tftp-server-5.2-33.oe2403sp3.aarch64.rpm"],"noarch":["tftp-help-5.2-33.oe2403sp3.noarch.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4660.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
