CVSS 3.1
6.5
MediumMetricsAV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
FreeRDP before 3.32.2 has a heap out-of-bounds write in the planar codec because freerdp bitmap planar context reset commits new dimensions before buffer reallocation succeeds, and a failed ResetGraphics is only logged. A malicious RDP server can send an oversized ResetGraphics PDU, then a GFX PLANAR command, to corrupt client heap memory and crash the client.
