{"id":"DEBIAN-CVE-2026-72712","details":"Nmap 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.","modified":"2026-09-25T08:47:30.799947013Z","published":"2026-08-11T18:18:23.550Z","upstream":["CVE-2026-72712"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-72712"}],"affected":[{"package":{"name":"nmap","ecosystem":"Debian:12","purl":"pkg:deb/debian/nmap?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.93+dfsg1-1","7.94+dfsg1-1","7.94+dfsg1-1~exp1","7.94+dfsg1-2","7.94+dfsg1-3","7.94+dfsg1-3~bpo12+1","7.94+dfsg1-4","7.94+git20230807.3be01efb1+dfsg-1","7.94+git20230807.3be01efb1+dfsg-1~bpo12+1","7.94+git20230807.3be01efb1+dfsg-2","7.94+git20230807.3be01efb1+dfsg-3","7.94+git20230807.3be01efb1+dfsg-4","7.94+git20230807.3be01efb1+dfsg-4~bpo12+1","7.95+dfsg-1","7.95+dfsg-2","7.95+dfsg-3","7.98+dfsg-1","7.98+dfsg-1~bpo13+1","7.99+dfsg-1","7.99+dfsg-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-72712.json"}},{"package":{"name":"nmap","ecosystem":"Debian:13","purl":"pkg:deb/debian/nmap?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.95+dfsg-3","7.98+dfsg-1","7.98+dfsg-1~bpo13+1","7.99+dfsg-1","7.99+dfsg-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-72712.json"}},{"package":{"name":"nmap","ecosystem":"Debian:14","purl":"pkg:deb/debian/nmap?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.95+dfsg-3","7.98+dfsg-1","7.98+dfsg-1~bpo13+1","7.99+dfsg-1","7.99+dfsg-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-72712.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
