{"id":"OESA-2026-3681","summary":"nmap security update","details":"Nmap (&amp;quot;Network Mapper&amp;quot;) is a free and open source (license) utility for network discovery and security \\ auditing. It was designed to rapidly scan large networks, but works fine against single hosts.\r\n\r\nSecurity Fix(es):\n\nNmap versions up to and including 7.99 contains a denial of service vulnerability that allows remote attackers to crash the application by sending a crafted packet containing a zero-length TCP option. The malformed packet forces the Packet:parse_options() function in nselib/packet.lua to allocate objects in an infinite loop, causing an out-of-memory condition that results in application crash.(CVE-2026-72712)","modified":"2026-09-05T15:16:35.502576486Z","published":"2026-09-05T15:03:52Z","upstream":["CVE-2026-72712"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3681"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72712"}],"affected":[{"package":{"name":"nmap","ecosystem":"openEuler:24.03-LTS-SP1","purl":"pkg:rpm/openEuler/nmap&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.94-11.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["nmap-7.94-11.oe2403sp1.aarch64.rpm","nmap-debuginfo-7.94-11.oe2403sp1.aarch64.rpm","nmap-debugsource-7.94-11.oe2403sp1.aarch64.rpm"],"noarch":["nmap-help-7.94-11.oe2403sp1.noarch.rpm"],"src":["nmap-7.94-11.oe2403sp1.src.rpm"],"x86_64":["nmap-7.94-11.oe2403sp1.x86_64.rpm","nmap-debuginfo-7.94-11.oe2403sp1.x86_64.rpm","nmap-debugsource-7.94-11.oe2403sp1.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-3681.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
