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 ...

The vulnerability of the RDPDR IRP RDP-client FreeRDP module allows a hacker to gain access to read, write, and delete arbitrary files.

The vulnerability of the RDPDR IRP RDP-client FreeRDP module is related to an incorrect limitation on the path name to the directory. Exploiting this vulnerability could allow a malicious actor to gain access to read, write, and delete arbitrary files...

Microsoft Windows TCPIP.SYS IppQualifyAddresses Out-of-Bounds Read Vulnerability

Summary An out-of-bounds read vulnerability exists in the IppQualifyAddresses function of the Microsoft Windows tcpip.sys driver. A specially crafted I/O request packet IRP can cause an arbitrary out-of-bounds read, potentially leading to information disclosure or a denial-of-service condition...
