{"id":"DEBIAN-CVE-2025-51006","details":"Within tcpreplay's tcprewrite, a double free vulnerability has been identified in the dlt_linuxsll2_cleanup() function in plugins/dlt_linuxsll2/linuxsll2.c. This vulnerability is triggered when tcpedit_dlt_cleanup() indirectly invokes the cleanup routine multiple times on the same memory region. By supplying a specifically crafted pcap file to the tcprewrite binary, a local attacker can exploit this flaw to cause a Denial of Service (DoS) via memory corruption.","modified":"2026-09-01T16:06:18.968057665Z","published":"2025-09-22T14:15:49.713Z","upstream":["CVE-2025-51006"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-51006"}],"affected":[{"package":{"name":"tcpreplay","ecosystem":"Debian:12","purl":"pkg:deb/debian/tcpreplay?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.4.3-1","4.4.4-1","4.5.1-1","4.5.2-1","4.5.3-1","4.5.4-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-51006.json"}},{"package":{"name":"tcpreplay","ecosystem":"Debian:13","purl":"pkg:deb/debian/tcpreplay?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.5.1-1","4.5.2-1","4.5.3-1","4.5.4-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-51006.json"}},{"package":{"name":"tcpreplay","ecosystem":"Debian:14","purl":"pkg:deb/debian/tcpreplay?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.5.2-1"}]}],"versions":["4.5.1-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-51006.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
