"The version of the Tenable Identity Exposure running on the remote host is prior to 3.77.16. It is, therefore, affected by
multiple vulnerabilities according to advisory TNS-2026-03:

  - Processing a malformed PKCS#12 file can trigger a NULL pointer dereference in the
    PKCS12_item_decrypt_d2i_ex() function, leading to a crash and Denial of Service for an application
    processing PKCS#12 files. (CVE-2025-69421)

  - Calling PKCS12_get_friendlyname() function on a maliciously crafted PKCS#12 file with a BMPString
    (UTF-16BE) friendly name containing non-ASCII BMP code point can trigger a one byte write before the
    allocated buffer, which can cause memory corruption leading to Denial of Service. (CVE-2025-69419)

  - An invalid or NULL pointer dereference can happen in an application processing a malformed PKCS#12 file,
    causing the application to dereference an invalid or NULL pointer on memory read, resulting in a Denial
    of Service. (CVE-2026-22795)

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