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 bitmap_cache_put. A malicious server can send a CACHE_BITMAP_ORDER (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.
AnalysisAI
FreeRDP versions prior to 3.24.0 contain a client-side heap out-of-bounds read/write vulnerability in the bitmap cache subsystem caused by an off-by-one boundary check error. A malicious RDP server can exploit this by sending a specially crafted CACHE_BITMAP_ORDER (Rev1) packet with cacheId equal to maxCells, allowing access to memory one element past the allocated array boundary. …
