The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1775223344 advisory.

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    Versions of FreeRDP on the 3.x release branch before beta3 are subject to a Use-After-Free in processing     `RDPGFX_CMDID_RESETGRAPHICS` packets. If `context->maxPlaneSize` is 0, `context->planesBuffer` will be     freed. However, without updating `context->planesBuffer`, this leads to a Use-After-Free exploit vector.
    In most environments this should only result in a crash. This issue has been addressed in version     3.0.0-beta3 and users of the beta 3.x releases are advised to upgrade. There are no known workarounds for     this vulnerability. (CVE-2023-39355)

  - FreeRDP is a free implementation of the Remote Desktop Protocol. Versions on the 2.x branch prior to to     2.11.8 and on the 3.x branch prior to 3.23.0 have an out-of-bounds read vulnerability in the FreeRDP     client's RDPGFX channel that allows a malicious RDP server to read uninitialized heap memory by sending a     crafted WIRE_TO_SURFACE_2 PDU with a `bitmapDataLength` value larger than the actual data in the packet.
    This can lead to information disclosure or client crashes when a user connects to a malicious server.
    Versions 2.11.8 and 3.23.0 fix the issue. (CVE-2026-25941)

  - FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0,     `xf_rail_server_execute_result` indexes the global `error_code_names[]` array (7 elements, indices 06)     with an unchecked `execResult->execResult` value received from the server, allowing an out-of-bounds read     when the server sends an `execResult` value of 7 or greater. Version 3.23.0 fixes the issue.
    (CVE-2026-25942)

  - FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0,     `xf_SetWindowMinMaxInfo` dereferences a freed `xfAppWindow` pointer because `xf_rail_get_window` in     `xf_rail_server_min_max_info` returns an unprotected pointer from the `railWindows` hash table, and the     main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread     is still using the pointer. Version 3.23.0 fixes the issue. (CVE-2026-25952)

  - FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0,     `xf_AppUpdateWindowFromSurface` reads from a freed `xfAppWindow` because the RDPGFX DVC thread obtains a     bare pointer via `xf_rail_get_window` without any lifetime protection, while the main thread can     concurrently delete the window through a fastpath window-delete order. Version 3.23.0 fixes the issue.
    (CVE-2026-25953)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
