FreeRDP: H.264 YUV Buffer Dimension Desync - Heap OOB Write

CVSS 7.5 HIGHEPSS 0.2%CWE-122CWE-131
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in yuv_ensure_buffer() in libfreerdp/codec/h264.c, h264->width and h264->height are updated before the reallocation loop. If any winpr_aligned_recalloc() call fails, the function returns FALSE but width/height are already inflated. This issue has been patched in version 3.24.2.
