Summary
FreeRDP has a heap-buffer-overflow in bitmap_cache_put via OOB cacheId
Details

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a client-side heap out-of-bounds read/write occurs in FreeRDP's bitmap cache subsystem due to an off-by-one boundary check in bitmapcacheput. A malicious server can send a CACHEBITMAPORDER (Rev1) with cacheId equal to maxCells, bypassing the guard and accessing cells[] one element past the allocated array. This vulnerability is fixed in 3.24.0.
