Описание
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, a client-side heap buffer overflow occurs in the RDPGFX ClearCodec decode path when maliciously crafted residual data causes out-of-bounds writes during color output. A malicious server can trigger a client-side heap buffer overflow, causing a crash (DoS) and potential heap corruption with code-execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.

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.

Описание
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, `xf_Pointer_New` frees `cursorPixels` on failure, then `pointer_free` calls `xf_Pointer_Free` and frees it again, triggering ASan UAF. A malicious server can trigger a client-side use after free, causing a crash (DoS) and potential heap corruption with code-execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, offscreen bitmap deletion leaves `gdi->drawing` pointing to freed memory, causing UAF when related update packets arrive. A malicious server can trigger a client-side use after free, causing a crash (DoS) and potential heap corruption with code-execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.
