{"id":"DEBIAN-CVE-2026-18313","details":"rpcapd can allocate up to 65536 bytes per each RPCAP_MSG_UPDATEFILTER_REQ or RPCAP_MSG_STARTCAP_REQ message received from the client, but it never frees the memory, so it leaks memory even under normal use.  A malicious client can cause the server to leak memory substantially faster.","modified":"2026-09-29T13:03:44.728060529Z","published":"2026-09-05T19:16:55.590Z","upstream":["CVE-2026-18313"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-18313"}],"affected":[{"package":{"name":"libpcap","ecosystem":"Debian:12","purl":"pkg:deb/debian/libpcap?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.3-1","1.10.4-1","1.10.4-2","1.10.4-3","1.10.4-4","1.10.4-4.1","1.10.4-4.1~exp1","1.10.4-5","1.10.4-5+hurd.1","1.10.5-1","1.10.5-2","1.10.6-1","1.10.6-2","1.10.7-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-18313.json"}},{"package":{"name":"libpcap","ecosystem":"Debian:13","purl":"pkg:deb/debian/libpcap?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.5-2","1.10.6-1","1.10.6-2","1.10.7-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-18313.json"}},{"package":{"name":"libpcap","ecosystem":"Debian:14","purl":"pkg:deb/debian/libpcap?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.10.7-1"}]}],"versions":["1.10.5-2","1.10.6-1","1.10.6-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-18313.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
