The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks) property. This allows attackers to create new valid signatures different from previous signatures for a known message.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-016772 advisory.

    The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability     and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks)     property. This allows attackers to create new valid signatures different from previous signatures for a     known message.

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability     and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks)     property. This allows attackers to create new valid signatures different from previous signatures for a     known message. (CVE-2020-36843)

Note that Nessus relies on the presence of the package as reported by the vendor.

The versions of Oracle Database Server installed on the remote host are affected by multiple vulnerabilities as referenced in the April 2025 CPU advisory.

  - Security-in-Depth issue in the Oracle Database Grid (Apache Tomcat) component of Oracle Database     Server. This vulnerability cannot be exploited in the context of this product. (CVE-2025-24813)

  - Vulnerability in the Oracle Database (OpenSSL) component of Oracle Database Server.  Supported versions     that are affected are 23.4-23.7. Easily exploitable vulnerability allows physical access to compromise     Oracle Database (OpenSSL).  Successful attacks of this vulnerability can result in  unauthorized update,     insert or delete access to some of Oracle Database (OpenSSL) accessible data as well as  unauthorized read     access to a subset of Oracle Database (OpenSSL) accessible data and unauthorized ability to cause a partial     denial of service (partial DOS) of Oracle Database (OpenSSL). CVSS 3.1 Base Score 4.3 (Confidentiality,     Integrity and Availability impacts). (CVE-2024-9143)

  - Vulnerability in the Oracle Database SQLCl (EdDSA) component of Oracle Database Server.  Supported versions     that are affected are 23.4-23.7. Easily exploitable vulnerability allows unauthenticated attacker with logon     to the infrastructure where Oracle Database SQLCl (EdDSA) executes to compromise Oracle Database SQLCl     (EdDSA).  While the vulnerability is in Oracle Database SQLCl (EdDSA), attacks may significantly impact     additional products (scope change).  Successful attacks of this vulnerability can result in  unauthorized     update, insert or delete access to some of Oracle Database SQLCl (EdDSA) accessible data. (CVE-2020-36843)

  - Vulnerability in the Oracle Database (OpenSSL) component of Oracle Database Server.  Supported versions     that are affected are 23.4-23.7. Easily exploitable vulnerability allows physical access to compromise     Oracle Database (OpenSSL).  Successful attacks of this vulnerability can result in  unauthorized update,     insert or delete access to some of Oracle Database (OpenSSL) accessible data as well as  unauthorized     read access to a subset of Oracle Database (OpenSSL) accessible data and unauthorized ability to cause     a partial denial of service (partial DOS) of Oracle Database (OpenSSL). (CVE-2022-3786)

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2025:1029-1 advisory.

    - CVE-2020-36843: Fixed no check performed on scalar to avoid signature malleability (bsc#1239551)

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

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

According to their self-reported version numbers, the version of Jenkins plugins running on the remote web server are affected by multiple vulnerabilities:

  - The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability     and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks)     property. This allows attackers to create new valid signatures different from previous signatures for a     known message. (CVE-2020-36843)
