"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-005335 advisory.

    Issue summary: Processing a malformed PKCS#12 file can trigger a NULL pointer
    dereference in the PKCS12_item_decrypt_d2i_ex() function.

    Impact summary: A NULL pointer dereference can trigger a crash which leads to
    Denial of Service for an application processing PKCS#12 files.

    The PKCS12_item_decrypt_d2i_ex() function does not check whether the oct
    parameter is NULL before dereferencing it. When called from
    PKCS12_unpack_p7encdata() with a malformed PKCS#12 file, this parameter can
    be NULL, causing a crash. The vulnerability is limited to Denial of Service
    and cannot be escalated to achieve code execution or memory disclosure.

    Exploiting this issue requires an attacker to provide a malformed PKCS#12 file
    to an application that processes it. For that reason the issue was assessed as
    Low severity according to our Security Policy.

    The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,
    as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary.

    OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are vulnerable to this issue.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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