Overview

Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the freerdp_image_copy_from_icon_data function. An attacker can cause an integer overflow by sending specially crafted icon data with large dimensions, which results in a miscalculated buffer size and bypasses bounds checks, allowing out-of-bounds memory access by a malicious RDP server.
