{"id":"DEBIAN-CVE-2025-14177","details":"In PHP versions:8.1.* before 8.1.34, 8.2.* before 8.2.30, 8.3.* before 8.3.29, 8.4.* before 8.4.16, 8.5.* before 8.5.1, the getimagesize() function may leak uninitialized heap memory into the APPn segments (e.g., APP1) when reading images in multi-chunk mode (such as via php://filter). This occurs due to a bug in php_read_stream_all_chunks() that overwrites the buffer without advancing the pointer, leaving tail bytes uninitialized. This may lead to information disclosure of sensitive heap data and affect the confidentiality of the target server.","modified":"2026-08-27T23:05:19.696324568Z","published":"2025-12-27T20:15:40.400Z","upstream":["CVE-2025-14177"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-14177"}],"affected":[{"package":{"name":"php8.2","ecosystem":"Debian:12","purl":"pkg:deb/debian/php8.2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.2.30-1~deb12u1"}]}],"versions":["8.2.10-1","8.2.10-2","8.2.12-1","8.2.16-1","8.2.16-2","8.2.17-1","8.2.18-1","8.2.18-1~deb12u1","8.2.20-1~deb12u1","8.2.20-2","8.2.20-3","8.2.21-1","8.2.23-1","8.2.24-1","8.2.24-1~deb12u1","8.2.26-1~deb12u1","8.2.26-4","8.2.27-1","8.2.28-1~deb12u1","8.2.29-1~deb12u1","8.2.5-2","8.2.7-1","8.2.7-1.1","8.2.7-1.2","8.2.7-1~deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-14177.json"}},{"package":{"name":"php8.4","ecosystem":"Debian:13","purl":"pkg:deb/debian/php8.4?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.16-1~deb13u1"}]}],"versions":["8.4.11-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-14177.json"}},{"package":{"name":"php8.4","ecosystem":"Debian:14","purl":"pkg:deb/debian/php8.4?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.16-1"}]}],"versions":["8.4.11-1","8.4.16-1~deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-14177.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
