Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a heap-buffer overflow occurred during drive reads when a server-controlled read length was used to read file data into an IRP output stream buffer without a hard upper limit. This allowed an oversized read ...

CVE-2026-110834 FreeRDP 2.0.0 before 3.32.0 Denial of Service via Serial IRP Null Handle

FreeRDP from 2.0.0 before 3.32.0 contains a null pointer dereference vulnerability that allows malicious RDP servers to crash clients by sending out-of-lifecycle serial IRPs. Attackers can send IRPMJREAD or IRPMJWRITE before create or after close, causing CommReadFile or CommWriteFile to...
