Executive Summary

This vulnerability exists in FreeRDP, a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, the software could render pixel data from adjacent heap memory to the screen. This means that data from memory areas next to the intended pixel data could be displayed, potentially exposing sensitive information to an attacker.

Impact Analysis

The vulnerability can lead to leakage of sensitive data because pixel data from adjacent heap memory is rendered to the screen. An attacker could exploit this to view information that should remain confidential, potentially compromising privacy or security.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade FreeRDP to version 3.24.2 or later, where the issue has been patched.

Compliance Impact

The vulnerability in FreeRDP prior to version 3.24.2 causes pixel data from adjacent heap memory to be rendered to the screen, potentially leaking sensitive data to an attacker.

Such leakage of sensitive data could have implications for compliance with data protection standards and regulations like GDPR and HIPAA, which require protection of sensitive information from unauthorized disclosure.

However, the provided information does not explicitly discuss the impact of this vulnerability on compliance with these standards or regulations.
