In FreeRDP less than or equal to 2.0.0, an Integer Overflow to Buffer Overflow exists. When using /video redirection, a manipulated server can instruct the client to allocate a buffer with a smaller size than requested due to an integer overflow in size calculation. With later messages, the server can manipulate the client to write data out of bound to the previously allocated buffer. This has been patched in 2.1.0.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.9, indicating it can be exploited remotely over the network but requires specific conditions to be met though user interaction is required and does not require pre-existing privileges . The vulnerability impacts integrity (unauthorized modifications), and limited availability for affected systems. Impacting 3 products from freerdp, from opensuse, from debian organizations running these solutions should prioritize assessment and patching.
Reported in 2020, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For freerdp's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
