{"id":"UBUNTU-CVE-2026-14454","details":"Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed. Imager mishandled large EXIF IFD entry count values, treating them as negative numbers.  This could lead to an attempt to allocate a block nearly the size of the address space, which fails and kills the process. An attacker could craft an image with EXIF data that terminates a worker process.","modified":"2026-07-15T19:45:23.431429030Z","published":"2026-07-08T13:16:00Z","upstream":["CVE-2026-14454"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-14454"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-14454"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/41637674/"}],"affected":[{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.003+dfsg-1","1.004+dfsg-1","1.004+dfsg-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libimager-perl","binary_version":"1.004+dfsg-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-14454.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.005+dfsg-2build1","1.006+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.006+dfsg-1","binary_name":"libimager-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-14454.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.011+dfsg-1","1.011+dfsg-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libimager-perl","binary_version":"1.011+dfsg-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-14454.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.012+dfsg-1build1","1.012+dfsg-2","1.012+dfsg-2build1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.012+dfsg-2build1","binary_name":"libimager-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-14454.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.019+dfsg-2","1.020+dfsg-1","1.022+dfsg-1","1.023+dfsg-1","1.023+dfsg-1build1","1.023+dfsg-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"libimager-perl","binary_version":"1.023+dfsg-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-14454.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.027+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.027+dfsg-1","binary_name":"libimager-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-14454.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.027+dfsg-1","1.029+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.029+dfsg-1","binary_name":"libimager-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-14454.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
