NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp2 package and not the freerdp2 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by sending an in-bounds region rectangle with an odd width.
