"The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2024-c702ea0fb1 advisory.

  - FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients and servers 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. No known workarounds are available. (CVE-2024-32459)

  - FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based based clients using
    `/bpp:32` legacy `GDI` drawing path with 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 modern drawing paths
    (e.g. `/rfx` or `/gfx` options). The workaround requires server side support. (CVE-2024-32460)

  - FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients using a version of
    FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to integer overflow and out-of-bounds write. Versions
    3.5.0 and 2.11.6 patch the issue. As a workaround, do not use `/gfx` options (e.g. deactivate with
    `/bpp:32` or `/rfx` as it is on by default). (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)

  - 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, deactivate `/gfx` (on by default, set `/bpp` or `/rfx` options instead.
    (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. This occurs when `WCHAR` string is read with twice the size it
    has and converted to `UTF-8`, `base64` decoded. The string is only used to compare against the redirection
    server certificate. Version 3.5.1 contains a patch for the issue. No known workarounds are available.
    (CVE-2024-32662)

  - 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. Version 3.5.1 contains a patch for the issue. No known
    workarounds are available. (CVE-2024-32658)

  - FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.5.1, a malicious
    server can crash the FreeRDP client by sending invalid huge allocation size. Version 3.5.1 contains a
    patch for the issue. No known workarounds are available. (CVE-2024-32660)

  - 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)

  - FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version
    3.5.1 are vulnerable to a possible `NULL` access and crash. Version 3.5.1 contains a patch for the issue.
    No known workarounds are available. (CVE-2024-32661)
