The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - freerdp: Integer Overflow leading to Heap Overflow in freerdp_bitmap_planar_context_reset (CVE-2024-22211)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    This issue affects Clients only. Integer underflow leading to DOS (e.g. abort due to `WINPR_ASSERT` with     default compilation flags). When an insufficient blockLen is provided, and proper length validation is not     performed, an Integer Underflow occurs, leading to a Denial of Service (DOS) vulnerability. This issue has     been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known     workarounds for this vulnerability. (CVE-2023-39350)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    Affected versions of FreeRDP are subject to a Null Pointer Dereference leading a crash in the RemoteFX     (rfx) handling. Inside the `rfx_process_message_tileset` function, the program allocates tiles using     `rfx_allocate_tiles` for the number of numTiles. If the initialization process of tiles is not completed     for various reasons, tiles will have a NULL pointer. Which may be accessed in further processing and would     cause a program crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised     to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-39351)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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

    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
