"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-005327 advisory.

    Issue summary: An application trying to decrypt CMS messages encrypted using
    password based encryption can trigger an out-of-bounds read and write.

    Impact summary: This out-of-bounds read may trigger a crash which leads to
    Denial of Service for an application. The out-of-bounds write can cause
    a memory corruption which can have various consequences including
    a Denial of Service or Execution of attacker-supplied code.

    Although the consequences of a successful exploit of this vulnerability
    could be severe, the probability that the attacker would be able to
    perform it is low. Besides, password based (PWRI) encryption support in CMS
    messages is very rarely used. For that reason the issue was assessed as
    Moderate severity according to our Security Policy.

    The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this
    issue, as the CMS implementation is outside the OpenSSL FIPS module
    boundary.

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.");
