FreeRDP has a heap-buffer-overflow in ecam_encoder_compress_h264

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, ecam_encoder_compress_h264 trusts server-controlled dimensions and does not validate the source buffer size, leading to an out-of-bounds read in sws_scale. This vulnerability is fixed in 3.22.0.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
