Attackers can send a raw bitmap cache order declaring large width, height, and bpp values with a tiny payload, causing memcpy() to read past the receive buffer and crash the client.","modified":"2026-10-20T05:00:06.766495219Z","published":"2026-10-19T22:47:36.095077952Z","upstream":["CVE-2026-112278"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-112278"}],"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-2026-112278.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-2026-112278.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-2026-112278.json"}}],"schema_version":"1.9.0"}
