{"id":"CVE-2026-27951","state":"PUBLISHED","title":"FreeRDP has possible Integer overflow in Stream_EnsureCapacity","description":"FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, the function `Stream_EnsureCapacity` can create an endless blocking loop. This may affect all client and server implementations using `FreeRDP`. For practical exploitation this will only work on 32bit systems where the available physical memory is `>= SIZE_MAX`. Version 3.23.0 contains a patch. No known workarounds are available.","publishedAt":"2026-02-25T21:07:30.828Z","updatedAt":"2026-02-25T21:43:56.822Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["FreeRDP FreeRDP"],"affected":[{"vendor":"FreeRDP","product":"FreeRDP","versions":[{"version":"< 3.23.0","status":"affected"}]}],"references":["https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-qcfc-ghxr-h927","https://github.com/FreeRDP/FreeRDP/commit/118afc0b954ba9d5632b7836ad24e454555ed113"],"weaknesses":["CWE-190"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/27xxx/CVE-2026-27951.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-27951","state":"PUBLISHED","datePublished":"2026-02-25T21:07:30.828Z","dateUpdated":"2026-02-25T21:43:56.822Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-25T03:11:36.690Z"},"containers":{"cna":{"title":"FreeRDP has possible Integer overflow in Stream_EnsureCapacity","descriptions":[{"lang":"en","value":"FreeRDP is a free implementation of the Remote Desktop Protocol.
