{"id":"CVE-2026-27951","summary":"FreeRDP has possible Integer overflow in Stream_EnsureCapacity","details":"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 `\u003e= SIZE_MAX`. Version 3.23.0 contains a patch. No known workarounds are available.","aliases":["GHSA-qcfc-ghxr-h927"],"modified":"2026-04-10T05:37:32.149642Z","published":"2026-02-25T21:07:30.828Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27951.json","cwe_ids":["CWE-190"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27951.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-qcfc-ghxr-h927"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27951"},{"type":"FIX","url":"https://github.com/FreeRDP/FreeRDP/commit/118afc0b954ba9d5632b7836ad24e454555ed113"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"0"},{"fixed":"b933ae18d9ad2a1d73c610868fcc30eb61654070"}]}],"versions":["1.0-beta1","1.0-beta2","1.0-beta4","1.0-beta5","1.0.0","1.0.1","1.1.0-beta+2013071101","1.1.0-beta1","1.1.0-beta1+android2","1.1.0-beta1+android3","1.1.0-beta1+android4","1.1.0-beta1+android5","1.1.0-beta1+ios1","1.1.0-beta1+ios2","1.1.0-beta1+ios3","1.1.0-beta1+ios4","1.2.0-beta1+android7","1.2.0-beta1+android9","2.0.0","2.0.0-beta1+android10","2.0.0-beta1+android11","2.0.0-rc0","2.0.0-rc1","2.0.0-rc2","2.0.0-rc3","2.0.0-rc4","3.0.0","3.0.0-beta1","3.0.0-beta2","3.0.0-beta3","3.0.0-beta4","3.0.0-rc0","3.1.0","3.2.0","3.3.0","3.4.0","3.5.0","3.5.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27951.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
