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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - FreeRDP before 3.31.0 contains an out-of-bounds read vulnerability in the URBDRC channel's     func_get_ep_desc function that indexes interface arrays by position instead of protocol field     InterfaceNumber. A malicious RDP server can send a crafted SELECT_CONFIGURATION message with permuted     InterfaceNumber values to read past allocated heap memory and crash the client. (CVE-2026-91956)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2026:76747 advisory.

    * FreeRDP: FreeRDP: Denial of Service via crafted Surface Bits command (CVE-2026-91954)
      * FreeRDP: FreeRDP: Remote code execution via heap buffer overflow in Server Redirection PDU     (CVE-2026-91964)
      * FreeRDP: FreeRDP: Denial of Service via out-of-bounds read in URBDRC channel (CVE-2026-91956)
      * FreeRDP: FreeRDP: Remote code execution via uninitialized heap memory disclosure (CVE-2026-91963)
      * FreeRDP: FreeRDP: Denial of Service due to buffer over-read in RPC gateway (CVE-2026-91959)
      * FreeRDP: FreeRDP: Heap buffer overflow via oversized LB_LOAD_BALANCE_INFO routing token can lead to     heap corruption. (CVE-2026-91953)
