Summary
FreeRDP has heap-buffer-overflow in Glyph_Alloc
Details

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, FastGlyph parsing trusts cbData/remaining length and never validates against the minimum size implied by cx/cy. A malicious server can trigger a client‑side global buffer overflow, causing a crash (DoS). Version 3.21.0 contains a patch for the issue.
