{"id":"UBUNTU-CVE-2018-7998","details":"In libvips before 8.6.3, a NULL function pointer dereference vulnerability was found in the vips_region_generate function in region.c, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted image file. This occurs because of a race condition involving a failed delayed load and other worker threads.","modified":"2026-01-30T02:47:37.405438Z","published":"2018-03-09T19:29:00Z","related":["USN-6437-1"],"upstream":["CVE-2018-7998"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-7998"},{"type":"REPORT","url":"https://github.com/jcupitt/libvips/commit/20d840e6da15c1574b3ed998bc92f91d1e36c2a5"},{"type":"REPORT","url":"https://github.com/libvips/libvips/issues/893"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6437-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-7998"}],"affected":[{"package":{"name":"vips","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/vips@8.2.2-1ubuntu0.1~esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.2.2-1ubuntu0.1~esm1"}]}],"versions":["7.40.6-2ubuntu2","8.0.2-2","8.2.1-1","8.2.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-vips-8.0","binary_version":"8.2.2-1ubuntu0.1~esm1"},{"binary_name":"libvips-dev","binary_version":"8.2.2-1ubuntu0.1~esm1"},{"binary_name":"libvips-tools","binary_version":"8.2.2-1ubuntu0.1~esm1"},{"binary_name":"libvips42","binary_version":"8.2.2-1ubuntu0.1~esm1"},{"binary_name":"python-vipscc","binary_version":"8.2.2-1ubuntu0.1~esm1"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-7998.json"}},{"package":{"name":"vips","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/vips@8.4.5-1ubuntu0.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.5-1ubuntu0.1~esm1"}]}],"versions":["8.4.5-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-vips-8.0","binary_version":"8.4.5-1ubuntu0.1~esm1"},{"binary_name":"libvips-dev","binary_version":"8.4.5-1ubuntu0.1~esm1"},{"binary_name":"libvips-tools","binary_version":"8.4.5-1ubuntu0.1~esm1"},{"binary_name":"libvips42","binary_version":"8.4.5-1ubuntu0.1~esm1"},{"binary_name":"python-vipscc","binary_version":"8.4.5-1ubuntu0.1~esm1"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-7998.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
