{"id":"DEBIAN-CVE-2026-120452","details":"libgphoto2 through 2.5.34 contains a heap out-of-bounds read and write vulnerability in jl2005bcd_decompress() that allows malicious USB cameras to corrupt heap memory via oversized thumbnail processing. Attackers can supply small allocation-table values and a thumbnail header byte so in-place byte-swapping exceeds the buffer by about 30 KB, leaking heap contents in preview images.","modified":"2026-11-04T13:02:12.611796056Z","published":"2026-11-02T15:17:28.553Z","upstream":["CVE-2026-120452"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-120452"}],"affected":[{"package":{"name":"libgphoto2","ecosystem":"Debian:12","purl":"pkg:deb/debian/libgphoto2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.30-1","2.5.31-1","2.5.31-2","2.5.31-2.1","2.5.31-2.1~exp1","2.5.31-3","2.5.31-4","2.5.32-1","2.5.33-1","2.5.34-1","2.5.34-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120452.json"}},{"package":{"name":"libgphoto2","ecosystem":"Debian:13","purl":"pkg:deb/debian/libgphoto2?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.31-4","2.5.32-1","2.5.33-1","2.5.34-1","2.5.34-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120452.json"}},{"package":{"name":"libgphoto2","ecosystem":"Debian:14","purl":"pkg:deb/debian/libgphoto2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.31-4","2.5.32-1","2.5.33-1","2.5.34-1","2.5.34-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120452.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:P/VC:L/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"}]}
