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.

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 remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-050266dc33 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.
