Summary

freerdp security update

Details

FreeRDP is a client implementation of the Remote Desktop Protocol (RDP) that follows Microsoft's open specifications. This package provides the client applications xfreerdp.

Security Fix(es):

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a heap buffer overflow vulnerability exists in the drive_process_irp_read function. When processing drive read requests, the function uses a server-controlled read length to copy file data into an IRP output stream buffer, but lacks a hard upper bound on this length. A malicious server can exploit this flaw by issuing an oversized read request, triggering a heap buffer overflow on the client side. This can lead to application crash (Denial of Service) and heap memory corruption, with potential code execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-22854)

Severity

6.8 (Medium)

Vulnerability from cvelistv5 – Published: 2026-01-14 17:47 – Updated: 2026-02-26 15:04

Title

FreeRDP has a heap-buffer-overflow in drive_process_irp_read

Summary

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a heap-buffer-overflow occurs in drive read when a server-controlled read length is used to read file data into an IRP output stream buffer without a hard upper bound, allowing an oversized read to overwrite heap memory. This vulnerability is fixed in 3.20.1.
