{"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":"2026-09-05T11:11:33.954350975Z","published":"2026-08-19T18:02:01.016Z","related":["ALSA-2026:61378"],"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":"75a1ec61d444179ea64a4ec0835214cb9c4f7c18"},{"fixed":"743f437f434c6814d3ba265c75cab14673bc2911"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"3.29.0"}]}}],"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/osv-test-cve-osv-conversion/osv-output/CVE-2026-69159.json","vanir_signatures_modified":"2026-08-21T08:10:19Z","vanir_signatures":[{"digest":{"line_hashes":["27849217718689435991094644549533067373","330466484407745871725736437760670491271","80073404428391480251712932393450173741","261001702374105619193270458760309755668","63675614114464460621665949122657701870","62009279958888338180346056134844185964","74150560493707942088160864300186752787","70925389120791971072611096487457394788","327814285679698029107220909819173221397","310640586733257055085103457471420890074","184323606363654880000914300897265591212","213803863262817505090339396184146089570","288487140662162537619658883480763855112","330535352613304883502346657432717482656","231053980863702437772785515408396792972","52759110020082854668681720004031191647","217872604885205727096975241901139257090","165711913403684607366050233056482056354","71421593515170996995518312805610525199","64860654166284036395545354433006354967","246244260403458151529397176318974116329","117538364606468935250934263228811690054","333074141710635353878506192750459148821","304881063991969741106492343000375513798","156582868962061421882097621119996987260","29154988636652661120278530386215818842","242158531111550419166868345863714063292","120624498408035481428454841931463883231","242934823772699756440916650077543221706","9845111677293244750558433704125257408","240658171763010388864740138699375570781","42189618431311834153659185052785430112","62009279958888338180346056134844185964","74150560493707942088160864300186752787","70925389120791971072611096487457394788","327814285679698029107220909819173221397","17387782426600102863121283949608853582","171953216901910294902162235053050328417","268844811168571583563133759091913084225","184467716870163907870314573302990440941","330535352613304883502346657432717482656","231053980863702437772785515408396792972","52759110020082854668681720004031191647","217872604885205727096975241901139257090","165711913403684607366050233056482056354","71421593515170996995518312805610525199","102046830557018794875598846466960760944","95255113091948098839760179836606697688","310807019588370299146564214757343785383","333074141710635353878506192750459148821","304881063991969741106492343000375513798","156582868962061421882097621119996987260","166636793809927508871583045932664331358","178348640798977195011925290645089812535","338342262528130457801918525779894704640","155386640405202161036468915226519349721","9845111677293244750558433704125257408"],"threshold":0.9},"id":"CVE-2026-69159-0880cffd","signature_type":"Line","signature_version":"v1","source":"https://github.com/freerdp/freerdp/commit/75a1ec61d444179ea64a4ec0835214cb9c4f7c18","target":{"file":"libfreerdp/codec/planar.c"},"deprecated":false}]}}],"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"}]}
