{"apiVersion":"1.0","identifier":"CVE-2026-63117","description":"FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, an authenticated RDP client can advertise DVI ADPCM with nBlockAlign equal to 8 and nChannels equal to 2 to make the `bs` calculation in rdpsnd_server_select_format in channels/rdpsnd/server/rdpsnd_main.c equal zero. The subsequent out_frames modulo `bs` operation raises SIGFPE and terminates the server-side rdpsnd channel process. This vulnerability fixed in 3.28.0.","publishedAt":"2026-08-19T18:17:08","lastModifiedAt":"2026-08-19T19:17:22","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63117","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00389,"riskScore":0.67,"affectedProduct":"FreeRDP","affectedVersions":"<3.28.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-63117","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-63117","en":"https://www.redsauce.net/en/cves/CVE-2026-63117","fr":"https://www.redsauce.net/fr/cves/CVE-2026-63117","pt":"https://www.redsauce.net/pt/cves/CVE-2026-63117","de":"https://www.redsauce.net/de/cves/CVE-2026-63117","sk":"https://www.redsauce.net/sk/cves/CVE-2026-63117","el":"https://www.redsauce.net/el/cves/CVE-2026-63117"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-63117"}}
