CVE-2024-22211

FreeRDP is a collection of remote desktop protocol library and client software that is both free and open source. An integer overflow within freerdp_bitmap_planar_context_reset results in a heap-buffer overflow. This impacts clients built on FreeRDP. However, server implementations and proxies based on FreeRDP are unaffected. A malevolent server could create a RDPGFX_RESET_GRAPHICS_PDU to allocate buffers that are too small, potentially causing subsequent out-of-bounds reads/writes. It's important to note that data extraction over the network is not feasible; these buffers are utilized solely for displaying images.

This vulnerability in FreeRDP, resulting from an integer overflow in certain versions, poses a low severity risk due to several mitigating factors. Firstly, it primarily affects FreeRDP-based clients, while server implementations and proxies remain unaffected. Additionally, the potential for exploitation is limited as it requires interaction with a malicious server, and data extraction over the network is not feasible; the vulnerability pertains solely to image display buffers.
