{"schemaVersion":3,"id":"UBUNTU-CVE-2024-8006","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Remote packet capture support is disabled by default in libpcap.  When a user builds libpcap with remote packet capture support enabled, one of the functions that become available is pcap_findalldevs_ex().  One of the function arguments can be a filesystem path, which normally means a directory with input data files.  When the specified path cannot be used as a directory, the function receives NULL from opendir(), but does not check the return value and passes the NULL value to readdir(), which causes a NULL pointer derefence.","dates":{"published":"2024-08-31T00:15:00.000Z","modified":"2026-02-05T03:36:53.590Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"ubuntu","product":"libpcap","name":"libpcap","label":"libpcap","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/libpcap","purlType":"deb","versions":[{"text":"All versions","noFixRecorded":true,"fixedIn":null}],"versionsText":"All versions (No fix recorded)","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/CVE-2024-8006","label":"ubuntu.com/security/CVE-2024-8006","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2024-8006","label":"www.cve.org/CVERecord?id=CVE-2024-8006","hostname":"www.cve.org","tags":["REPORT"]},{"url":"https://github.com/the-tcpdump-group/libpcap/commit/0f8a103469ce87d2b8d68c5130a46ddb7fb5eb29","label":"github.com/the-tcpdump-group/libpcap/commit/0f8a103469ce87d2b8d68c5130a46ddb7fb5eb29","hostname":"github.com","tags":["REPORT"]},{"url":"https://github.com/the-tcpdump-group/libpcap/commit/8a633ee5b9ecd9d38a587ac9b204e2380713b0d6","label":"github.com/the-tcpdump-group/libpcap/commit/8a633ee5b9ecd9d38a587ac9b204e2380713b0d6","hostname":"github.com","tags":["REPORT"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":["CVE-2024-8006"]},"timeline":[{"kind":"published","date":"2024-08-31T00:15:00.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-02-05T03:36:53.590Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-19T16:26:20.347Z","stale":false,"partial":false}}
