{"id":"UBUNTU-CVE-2025-52886","details":"Poppler is a PDF rendering library. Versions prior to 25.06.0 use `std::atomic_int` for reference counting. Because `std::atomic_int` is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue.","modified":"2026-01-30T02:52:09.246399Z","published":"2025-07-02T16:15:00Z","related":["USN-7675-1","USN-7687-1"],"upstream":["CVE-2025-52886"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-52886"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-52886"},{"type":"REPORT","url":"https://securitylab.github.com/advisories/GHSL-2025-054_poppler/"},{"type":"REPORT","url":"https://gitlab.freedesktop.org/poppler/poppler/-/merge_requests/1828"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7675-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7687-1"}],"affected":[{"package":{"name":"poppler","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/poppler@0.41.0-0ubuntu1.16+esm7?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.41.0-0ubuntu1.16+esm7"}]}],"versions":["0.33.0-0ubuntu3","0.37.0-0ubuntu1","0.38.0-0ubuntu1","0.41.0-0ubuntu1","0.41.0-0ubuntu1.1","0.41.0-0ubuntu1.2","0.41.0-0ubuntu1.3","0.41.0-0ubuntu1.4","0.41.0-0ubuntu1.5","0.41.0-0ubuntu1.6","0.41.0-0ubuntu1.7","0.41.0-0ubuntu1.8","0.41.0-0ubuntu1.9","0.41.0-0ubuntu1.10","0.41.0-0ubuntu1.11","0.41.0-0ubuntu1.12","0.41.0-0ubuntu1.13","0.41.0-0ubuntu1.14","0.41.0-0ubuntu1.15","0.41.0-0ubuntu1.16","0.41.0-0ubuntu1.16+esm1","0.41.0-0ubuntu1.16+esm2","0.41.0-0ubuntu1.16+esm3","0.41.0-0ubuntu1.16+esm4","0.41.0-0ubuntu1.16+esm5","0.41.0-0ubuntu1.16+esm6"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-poppler-0.18","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-cpp-dev","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-cpp0","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-dev","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-glib-dev","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-glib8","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-private-dev","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-qt4-4","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-qt4-dev","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-qt5-1","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler-qt5-dev","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"libpoppler58","binary_version":"0.41.0-0ubuntu1.16+esm7"},{"binary_name":"poppler-utils","binary_version":"0.41.0-0ubuntu1.16+esm7"}],"availability":"Available
