{"id":"DEBIAN-CVE-2026-126050","details":"apitrace 2.0 through 14.0 contains a heap-based buffer overflow in SnappyFile::flushReadCache() that allows attackers to write past m_compressedCache via an oversized compressed chunk length. Attackers can supply a crafted .trace file whose 4-byte chunk length exceeds the fixed buffer size, corrupting heap memory when users dump, inspect, or replay it.","modified":"2026-11-11T19:00:06.359976498Z","published":"2026-11-10T17:17:32.107Z","upstream":["CVE-2026-126050"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-126050"}],"affected":[{"package":{"name":"apitrace","ecosystem":"Debian:12","purl":"pkg:deb/debian/apitrace?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.1+repack-1.1","11.1+repack-1.2","11.1+repack-2","11.1+repack-2.1","13.0+repack-1","13.0+repack-1.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-126050.json"}},{"package":{"name":"apitrace","ecosystem":"Debian:13","purl":"pkg:deb/debian/apitrace?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.1+repack-2","11.1+repack-2.1","13.0+repack-1","13.0+repack-1.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-126050.json"}},{"package":{"name":"apitrace","ecosystem":"Debian:14","purl":"pkg:deb/debian/apitrace?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.1+repack-2","11.1+repack-2.1","13.0+repack-1","13.0+repack-1.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-126050.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/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"}]}
