{"id":"USN-7589-1","summary":"gnuplot vulnerabilities","details":"Tim Blazytko, Cornelius Aschermann, Sergej Schumilo, and Nils Bars\ndiscovered that Gnuplot had several memory-related issues. 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)","modified":"2026-02-10T04:49:02Z","published":"2025-06-23T12:12:04Z","related":["UBUNTU-CVE-2018-19490","UBUNTU-CVE-2018-19491","UBUNTU-CVE-2018-19492","UBUNTU-CVE-2020-25412","UBUNTU-CVE-2020-25559","UBUNTU-CVE-2020-25969","UBUNTU-CVE-2021-44917"],"upstream":["CVE-2018-19490","CVE-2018-19491","CVE-2018-19492","CVE-2020-25412","CVE-2020-25559","CVE-2020-25969","CVE-2021-44917","UBUNTU-CVE-2018-19490","UBUNTU-CVE-2018-19491","UBUNTU-CVE-2018-19492","UBUNTU-CVE-2020-25412","UBUNTU-CVE-2020-25559","UBUNTU-CVE-2020-25969","UBUNTU-CVE-2021-44917"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7589-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-19490"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-19491"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-19492"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-25412"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-25559"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-25969"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-44917"}],"affected":[{"package":{"name":"gnuplot","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/gnuplot@4.6.4-2ubuntu0.1~esm1?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.6.4-2ubuntu0.1~esm1"}]}],"versions":["4.6.3-2","4.6.4-1","4.6.4-2"],"ecosystem_specific":{"binaries":[{"binary_version":"4.6.4-2ubuntu0.1~esm1","binary_name":"gnuplot"},{"binary_version":"4.6.4-2ubuntu0.1~esm1","binary_name":"gnuplot-nox"},{"binary_version":"4.6.4-2ubuntu0.1~esm1","binary_name":"gnuplot-qt"},{"binary_version":"4.6.4-2ubuntu0.1~esm1","binary_name":"gnuplot-x11"}],"availability":"Available
