Vulnerability from cvelistv5
Published

Modified

Severity ?
5.3 (Medium) - CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:N/I:H/A:N
Summary
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. In affected versions a malicious server might trigger out of bound writes in a connected client. Connections using GDI or SurfaceCommands to send graphics updates to the client might send `0` width/height or out of bound rectangles to trigger out of bound writes. With `0` width or heigth the memory allocation will be `0` but the missing bounds checks allow writing to the pointer at this (not allocated) region. This issue has been patched in FreeRDP 2.4.1.
