{"id":"CVE-2026-69159","summary":"FreeRDP: Out-of-Bounds Read in Planar RLE Decoder (planar_decompress_plane_rle / planar_decompress_plane_rle_only)","details":"FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.29.0, planar_decompress_plane_rle and planar_decompress_plane_rle_only in libfreerdp/codec/planar.c verify that a control byte exists but do not verify that the source buffer contains the zero to fifteen raw bytes declared by that control byte. A malicious RDP server can send a truncated planar bitmap or surface update whose final control byte claims additional raw bytes, causing the decoder to read beyond pSrcData while processing a color plane. This can crash the client and may disclose adjacent memory. This issue is fixed in version 3.29.0.","aliases":["CVE-2026-67306","GHSA-qrxx-7g3c-j6w3"],"modified":"2026-08-23T03:49:32.217115243Z","published":"2026-08-19T18:02:01.016Z","database_specific":{"cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/69xxx/CVE-2026-69159.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/FreeRDP/FreeRDP/releases/tag/3.29.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/69xxx/CVE-2026-69159.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-qrxx-7g3c-j6w3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-69159"},{"type":"FIX","url":"https://github.com/FreeRDP/FreeRDP/commit/75a1ec61d444179ea64a4ec0835214cb9c4f7c18"},{"type":"FIX","url":"https://github.com/FreeRDP/FreeRDP/pull/13016"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"0"},{"fixed":"743f437f434c6814d3ba265c75cab14673bc2911"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.29.0"}],"source":"AFFECTED_FIELD"}}],"versions":["3.5.1","3.5.0","3.4.0","3.3.0","3.2.0","3.1.0","3.0.0","3.0.0-rc0","3.0.0-beta4","3.0.0-beta3","3.0.0-beta2","3.0.0-beta1","2.0.0","2.0.0-rc4","2.0.0-rc3","2.0.0-rc2","2.0.0-rc1","2.0.0-rc0","2.0.0-beta1+android11","2.0.0-beta1+android10","1.2.0-beta1+android9","1.2.0-beta1+android7","1.1.0-beta+2013071101","1.1.0-beta1+ios4","1.1.0-beta1+android5","1.1.0-beta1+android4","1.1.0-beta1+ios3","1.1.0-beta1+ios2","1.1.0-beta1+android3","1.1.0-beta1+android2","1.1.0-beta1+ios1","1.1.0-beta1","1.0.1","1.0.0","1.0-beta5","1.0-beta4","1.0-beta2","1.0-beta1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-69159.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L"}]}
