{"id":"DEBIAN-CVE-2026-112277","details":"rdesktop through 1.9.0 contains a heap out-of-bounds read vulnerability in process_plane() in bitmap.c that allows malicious RDP servers to crash clients by sending malformed 32 bpp compressed bitmaps. Attackers can declare a large bitmap geometry with a short compressed body in bitmap update PDUs or bitmap cache orders, causing unbounded reads past the receive buffer and denial of service.","modified":"2026-10-23T18:05:00.065769212Z","published":"2026-10-19T14:17:05.663Z","upstream":["CVE-2026-112277"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-112277"}],"affected":[{"package":{"name":"rdesktop","ecosystem":"Debian:12","purl":"pkg:deb/debian/rdesktop?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.9.0-2","1.9.0-3"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-112277.json"}},{"package":{"name":"rdesktop","ecosystem":"Debian:13","purl":"pkg:deb/debian/rdesktop?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.9.0-2","1.9.0-3"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-112277.json"}},{"package":{"name":"rdesktop","ecosystem":"Debian:14","purl":"pkg:deb/debian/rdesktop?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.9.0-2","1.9.0-3"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-112277.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/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"}]}
