{"id":"CVE-2026-29775","summary":"FreeRDP has a heap-buffer-overflow in bitmap_cache_put via OOB cacheId","details":"FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a client-side heap out-of-bounds read/write occurs in FreeRDP's bitmap cache subsystem due to an off-by-one boundary check in bitmap_cache_put. A malicious server can send a CACHE_BITMAP_ORDER (Rev1) with cacheId equal to maxCells, bypassing the guard and accessing cells[] one element past the allocated array. This vulnerability is fixed in 3.24.0.","aliases":["GHSA-h666-rfw3-jhvj"],"modified":"2026-05-16T14:15:02.707584539Z","published":"2026-03-13T17:28:39.641Z","related":["ALSA-2026:16014","ALSA-2026:16019","ALSA-2026:16482","SUSE-SU-2026:1632-1","SUSE-SU-2026:1633-1","SUSE-SU-2026:1634-1","SUSE-SU-2026:1635-1","SUSE-SU-2026:1640-1","SUSE-SU-2026:21436-1","openSUSE-SU-2026:10408-1","openSUSE-SU-2026:20657-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29775.json","cwe_ids":["CWE-787"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29775.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-h666-rfw3-jhvj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29775"},{"type":"FIX","url":"https://github.com/FreeRDP/FreeRDP/commit/ffad58fd2b329efd81a3239e9d7e3c927b8e503f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"0"},{"fixed":"b00402d3258402c868224b6ffed04182cbed78d9"}]}],"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-2026-29775.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"}]}
