Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
Out-of-bounds read in FreeRDP's planar RLE bitmap decoder allows a malicious RDP server to crash connecting clients and potentially disclose adjacent heap or stack memory. The flaw exists in planar_decompress_plane_rle and planar_decompress_plane_rle_only within libfreerdp/codec/planar.c across all FreeRDP releases prior to 3.29.0. …

Vulnerability AssessmentAI
| Exploitation | The victim FreeRDP client must actively initiate or be redirected to an RDP connection with a malicious or attacker-controlled RDP server - the server is the attacker's platform, not the client. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L scores at 5.4 Medium, which appropriately reflects the attack's dependency on user interaction - the victim must actively connect to the malicious RDP server. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary fix is upgrading to FreeRDP 3.29.0 or later, released at https://github.com/FreeRDP/FreeRDP/releases/tag/3.29.0. … Detailed patch versions, workarounds, and compensating controls in full report. |
