"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1225 advisory.

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

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

    Although the consequences of a successful exploit of this vulnerabilitycould be severe, the probability
    that the attacker would be able toperform it is low. Besides, password based (PWRI) encryption support in
    CMSmessages is very rarely used. For that reason the issue was assessed asModerate 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 thisissue, as the CMS
    implementation is outside the OpenSSL FIPS moduleboundary. (CVE-2025-9230)

    Issue summary: A timing side-channel which could potentially allow remoterecovery of the private key
    exists in the SM2 algorithm implementation on 64 bitARM platforms.

    Impact summary: A timing side-channel in SM2 signature computations on 64 bitARM platforms could allow
    recovering the private key by an attacker..

    While remote key recovery over a network was not attempted by the reporter,timing measurements revealed a
    timing signal which may allow such an attack.

    OpenSSL does not directly support certificates with SM2 keys in TLS, and sothis CVE is not relevant in
    most TLS contexts.  However, given that it ispossible to add support for such certificates via a custom
    provider, coupledwith the fact that in such a custom provider context the private key may berecoverable
    via remote timing measurements, we consider this to be a Moderateseverity issue.

    The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by thisissue, as SM2 is not an
    approved algorithm. (CVE-2025-9231)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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