The version of freerdp installed on the remote host is prior to 2.11.7-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2537 advisory.

    2024-06-06: CVE-2024-32660 was added to this advisory.

    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. (CVE-2024-22211)

    Integer overflow & OutOfBound Write in clear_decompress_residual_data

    NOTE: https://www.freerdp.com/2024/04/17/2_11_6-release (CVE-2024-32039)

    FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients that use a version     of FreeRDP prior to 3.5.0 or 2.11.6 and have connections to servers using the `NSC` codec are vulnerable     to integer underflow. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, do not use the NSC codec     (e.g. use `-nsc`). (CVE-2024-32040)

    OutOfBound Read in zgfx_decompress_segment

    NOTE: https://www.freerdp.com/2024/04/17/2_11_6-release (CVE-2024-32041)

    FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients that use a version     of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch     the issue. As a workaround, use `/gfx` or `/rfx` modes (on by default, require server side support).
    (CVE-2024-32458)

    FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version     3.5.1 are vulnerable to out-of-bounds read if `((nWidth == 0) and (nHeight == 0))`. Version 3.5.1 contains     a patch for the issue. No known workarounds are available. (CVE-2024-32659)
