{"id":"DEBIAN-CVE-2026-111151","details":"OpenJPH through 0.32.0 contains a heap out-of-bounds write vulnerability in the HTJ2K cleanup-pass decoder that allows attackers to corrupt memory via one-row codeblocks. Attackers can supply a crafted .j2c or .jph codestream with small precinct sizes, causing the decoder to write a second row past the codeblock buffer, resulting in memory corruption and crashes.","modified":"2026-10-16T07:00:06.254952443Z","published":"2026-10-15T19:17:29.800Z","upstream":["CVE-2026-111151"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-111151"}],"affected":[{"package":{"name":"openjph","ecosystem":"Debian:12","purl":"pkg:deb/debian/openjph?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.3-1","0.10.3-2","0.18.2-1","0.18.2-1.1","0.18.2-2","0.21.0-1","0.21.0-1.1","0.21.2-1","0.21.5-1","0.21.5-2","0.25.3-1","0.26.0-1","0.26.3-1","0.27.0-1","0.27.3-1","0.28.1-1","0.32.0-1","0.9.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111151.json"}},{"package":{"name":"openjph","ecosystem":"Debian:13","purl":"pkg:deb/debian/openjph?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.21.2-1","0.21.5-1","0.21.5-2","0.25.3-1","0.26.0-1","0.26.3-1","0.27.0-1","0.27.3-1","0.28.1-1","0.32.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111151.json"}},{"package":{"name":"openjph","ecosystem":"Debian:14","purl":"pkg:deb/debian/openjph?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.21.2-1","0.21.5-1","0.21.5-2","0.25.3-1","0.26.0-1","0.26.3-1","0.27.0-1","0.27.3-1","0.28.1-1","0.32.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111151.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
