"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-007124 advisory.

    Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL
    to crash leading to a potential Denial of Service attack

    Impact summary: Applications loading files in the PKCS12 format from untrusted
    sources might terminate abruptly.

    A file in PKCS12 format can contain certificates and keys and may come from an
    untrusted source. The PKCS12 specification allows certain fields to be NULL, but
    OpenSSL does not correctly check for this case. This can lead to a NULL pointer
    dereference that results in OpenSSL crashing. If an application processes PKCS12
    files from an untrusted source using the OpenSSL APIs then that application will
    be vulnerable to this issue.

    OpenSSL APIs that are vulnerable to this are: PKCS12_parse(),
    PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes()
    and PKCS12_newpass().

    We have also fixed a similar issue in SMIME_write_PKCS7(). However since this
    function is related to writing data we do not consider it security significant.

    The FIPS modules in 3.2, 3.1 and 3.0 are not affected by 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.");
