FreeRDP is a set of free and open source remote desktop protocol library and clients. In affected versions an integer overflow in `freerdp_bitmap_planar_context_reset` leads to heap-buffer overflow. This affects FreeRDP based clients. FreeRDP based server implementations and proxy are not affected. A malicious server could prepare a `RDPGFX_RESET_GRAPHICS_PDU` to allocate too small buffers, possibly triggering later out of bound read/write. Data extraction over network is not possible, the buffers are used to display an image. This issue has been addressed in version 2.11.5 and 3.2.0. Users are advised to upgrade. there are no know workarounds for this vulnerability. https://github.com/FreeRDP/FreeRDP/commit/939e922936e9c3ae8fc204968645e5e7563a2fff https://github.com/FreeRDP/FreeRDP/commit/aeac3040cc99eeaff1e1171a822114c857b9dca9 https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-rjhp-44rv-7v59

I don't understand why its marked as Important with CVSS: 3.7 Rohit, Can you explain a bit! Also RHEL-7 tracker is created for Y-stream that is not present, only z-stream tracker is present. (eg. RHEL-7.9.z)
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.
