Information Disclosure Buffer Overflow

Description

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, pixel data from adjacent heap memory is rendered to screen, potentially leaking sensitive data to the attacker. This issue has been patched in version 3.24.2.

Analysis

FreeRDP versions prior to 3.24.2 leak sensitive heap data to the screen during pixel rendering in remote desktop sessions, allowing unauthenticated remote attackers to obtain confidential information through a man-in-the-middle position or compromised RDP server. The vulnerability requires user interaction (UI:R) and involves out-of-bounds memory read (CWE-125), with CVSS 5.9 reflecting moderate confidentiality impact and low availability degradation. …
