{"id":"UBUNTU-CVE-2025-34450","details":"merbanan/rtl_433 versions up to and including 25.02 and prior to commit 25e47f8 contain a stack-based buffer overflow vulnerability in the function parse_rfraw() located in src/rfraw.c. When processing crafted or excessively large raw RF input data, the application may write beyond the bounds of a stack buffer, resulting in memory corruption or a crash. This vulnerability can be exploited to cause a denial of service and, under certain conditions, may be leveraged for further exploitation depending on the execution environment and available mitigations.","modified":"2026-05-20T16:21:24.203022600Z","published":"2025-12-18T22:15:00Z","upstream":["CVE-2025-34450"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-34450"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-34450"},{"type":"REPORT","url":"https://github.com/dd32/rtl_433/commit/25e47f8"},{"type":"REPORT","url":"https://github.com/marlinkcyber/advisories/blob/main/advisories/MCSAID-2025-004-rtl_433-rfraw-parse-overflow.md"},{"type":"REPORT","url":"https://github.com/merbanan/rtl_433/issues/3375"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/merbanan-rtl-433-stack-based-buffer-overflow"}],"affected":[{"package":{"name":"rtl-433","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["19.08-1","19.08-1build1","19.08-2","20.02-1"],"ecosystem_specific":{"binaries":[{"binary_version":"20.02-1","binary_name":"rtl-433"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34450.json"}},{"package":{"name":"rtl-433","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20.11-1","21.05-2","21.05-2build1","21.12-1"],"ecosystem_specific":{"binaries":[{"binary_version":"21.12-1","binary_name":"rtl-433"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34450.json"}},{"package":{"name":"rtl-433","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["22.11-1","23.11-1","23.11-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"23.11-1build1","binary_name":"rtl-433"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34450.json"}},{"package":{"name":"rtl-433","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.02-1"],"ecosystem_specific":{"binaries":[{"binary_version":"25.02-1","binary_name":"rtl-433"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34450.json"}},{"package":{"name":"rtl-433","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.02-1","25.02-1.1","25.12-1"],"ecosystem_specific":{"binaries":[{"binary_version":"25.12-1","binary_name":"rtl-433"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34450.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
