{"id":"OESA-2026-3679","summary":"nmap security update","details":"Nmap ("Network Mapper") 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":"2026-09-05T15:16:35.343641568Z","published":"2026-09-05T15:03:51Z","upstream":["CVE-2026-72712"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3679"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72712"}],"affected":[{"package":{"name":"nmap","ecosystem":"openEuler:20.03-LTS-SP4","purl":"pkg:rpm/openEuler/nmap&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.80-7.oe2003sp4"}]}],"ecosystem_specific":{"src":["nmap-7.80-7.oe2003sp4.src.rpm"],"x86_64":["nmap-7.80-7.oe2003sp4.x86_64.rpm","nmap-debuginfo-7.80-7.oe2003sp4.x86_64.rpm","nmap-debugsource-7.80-7.oe2003sp4.x86_64.rpm"],"aarch64":["nmap-7.80-7.oe2003sp4.aarch64.rpm","nmap-debuginfo-7.80-7.oe2003sp4.aarch64.rpm","nmap-debugsource-7.80-7.oe2003sp4.aarch64.rpm"],"noarch":["nmap-help-7.80-7.oe2003sp4.noarch.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-3679.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"}]}
