{"id":"UBUNTU-CVE-2026-70652","details":"libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, libvips built with libultrahdr support can incorrectly size an output buffer in libvips/foreign/uhdrsave.c within vips_foreign_save_uhdr_set_raw_hdr when a pipeline enlarges an incoming JPEG to a very large output before encoding a gain map through VipsForeignSaveUhdr. The undersized allocation can cause a heap buffer over-read that may disclose adjacent data or crash the process. This issue is fixed in version 8.18.3.","modified":"2026-09-14T16:32:02.828927065Z","published":"2026-08-20T21:17:00Z","upstream":["CVE-2026-70652"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-70652"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-70652"},{"type":"REPORT","url":"https://github.com/libvips/libvips/security/advisories/GHSA-h27h-jf9v-m8rg"},{"type":"REPORT","url":"https://github.com/libvips/libvips/pull/5039"}],"affected":[{"package":{"name":"vips","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/vips?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.40.6-2ubuntu2","8.0.2-2","8.2.1-1","8.2.2-1","8.2.2-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"8.2.2-1ubuntu0.1~esm1","binary_name":"gir1.2-vips-8.0"},{"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"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-70652.json"}},{"package":{"name":"vips","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/vips?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.4.5-1build1","8.4.5-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"8.4.5-1ubuntu0.1~esm1","binary_name":"gir1.2-vips-8.0"},{"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"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-70652.json"}},{"package":{"name":"vips","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/vips?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.7.4-1build1","8.8.3-3","8.8.3-3ubuntu1","8.9.0-1","8.9.0-1build1","8.9.1-1","8.9.1-2","8.9.1-2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"8.9.1-2ubuntu0.1~esm1","binary_name":"gir1.2-vips-8.0"},{"binary_name":"libvips-tools","binary_version":"8.9.1-2ubuntu0.1~esm1"},{"binary_name":"libvips42","binary_version":"8.9.1-2ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-70652.json"}},{"package":{"name":"vips","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/vips?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.10.5-2ubuntu1","8.11.4-2","8.12.1-1","8.12.1-1build1","8.12.1-1ubuntu0.1~esm1","8.12.1-1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"8.12.1-1ubuntu0.1~esm2","binary_name":"gir1.2-vips-8.0"},{"binary_name":"libvips-tools","binary_version":"8.12.1-1ubuntu0.1~esm2"},{"binary_name":"libvips42","binary_version":"8.12.1-1ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-70652.json"}},{"package":{"name":"vips","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/vips?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.14.3-1","8.14.5-1","8.15.0-1","8.15.0-2","8.15.1-1","8.15.1-1build1","8.15.1-1.1build3","8.15.1-1.1build4","8.15.1-1.1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-vips-8.0","binary_version":"8.15.1-1.1ubuntu0.1~esm1"},{"binary_name":"libvips-tools","binary_version":"8.15.1-1.1ubuntu0.1~esm1"},{"binary_name":"libvips42t64","binary_version":"8.15.1-1.1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-70652.json"}},{"package":{"name":"vips","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/vips?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.16.1-1","8.16.1-2","8.17.3-2","8.18.0-1","8.18.0-1build1","8.18.0-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-vips-8.0","binary_version":"8.18.0-1ubuntu0.1~esm1"},{"binary_version":"8.18.0-1ubuntu0.1~esm1","binary_name":"libvips-tools"},{"binary_version":"8.18.0-1ubuntu0.1~esm1","binary_name":"libvips42t64"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-70652.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
