An\nattacker could possibly use these issues to cause Gnuplot to\nexperience a buffer overflow, resulting in a denial of service or\narbitrary code execution. These issues only affected Ubuntu\n14.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-19490, CVE-2018-19491,\nCVE-2018-19492)\n\nIt was discovered that Gnuplot could write out-of-bounds due to\nthe use of strncpy(). An attacker could possibly use this issue\nto enable the execution of arbitrary code. This issue only\naffected Ubuntu 20.04 LTS. (CVE-2020-25412)\n\nIt was discovered that Gnuplot incorrectly freed memory when\nexecuting print_set_output(). An attacker could possibly use this\nissue to enable the execution of arbitrary code. (CVE-2020-25559)\n\nIt was discovered that Gnuplot's plotrequest() function contained\na buffer overflow. An attacker could possibly use this issue to\ncause Gnuplot to crash, resulting in a denial of service or\narbitrary code execution. (CVE-2020-25969)\n\nIt was discovered that Gnuplot's boundary3d() function could be\nmade to divide by zero. An attacker could possibly use this issue\nto cause Gnuplot to crash, resulting in a denial of service.\n(CVE-2021-44917)","dates":{"published":"2025-06-23T12:12:04.000Z","modified":"2026-06-25T13:32:30.390Z","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":"gnuplot","name":"gnuplot","label":"gnuplot","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/gnuplot","purlType":"deb","versions":[{"text":"< 4.6.4-2ubuntu0.1~esm1","noFixRecorded":false,"fixedIn":null},{"text":"< 4.6.6-3ubuntu0.1+esm1","noFixRecorded":false,"fixedIn":null},{"text":"< 5.2.2+dfsg1-2ubuntu1+esm1","noFixRecorded":false,"fixedIn":null},{"text":"< 5.2.8+dfsg1-2ubuntu0.1~esm1","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 4.6.4-2ubuntu0.1~esm1 | < 4.6.6-3ubuntu0.1+esm1 | < 5.2.2+dfsg1-2ubuntu1+esm1 | < 5.2.8+dfsg1-2ubuntu0.1~esm1","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/notices/USN-7589-1","label":"ubuntu.com/security/notices/USN-7589-1","hostname":"ubuntu.com","tags":["Advisory"]},{"url":"https://ubuntu.com/security/CVE-2018-19490","label":"ubuntu.com/security/CVE-2018-19490","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2018-19491","label":"ubuntu.com/security/CVE-2018-19491","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2018-19492","label":"ubuntu.com/security/CVE-2018-19492","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2020-25412","label":"ubuntu.com/security/CVE-2020-25412","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2020-25559","label":"ubuntu.com/security/CVE-2020-25559","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2020-25969","label":"ubuntu.com/security/CVE-2020-25969","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2021-44917","label":"ubuntu.com/security/CVE-2021-44917","hostname":"ubuntu.com","tags":["REPORT"]}],"lineage":{"upstream":["CVE-2018-19490","CVE-2018-19491","CVE-2018-19492","CVE-2020-25412","CVE-2020-25559","CVE-2020-25969","CVE-2021-44917"],"downstream":[],"duplicates":[],"related":["CVE-2018-19490","CVE-2018-19491","CVE-2018-19492","CVE-2020-25412","CVE-2020-25559","CVE-2020-25969","CVE-2021-44917"]},"timeline":[{"kind":"published","date":"2025-06-23T12:12:04.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-06-25T13:32:30.390Z","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":"2026-10-20T09:18:38.448Z","stale":false,"partial":false}}
