An issue was discovered in the Bouncy Castle Crypto Package For Java before BC TLS Java 1.0.19 (ships with BC Java 1.78, BC Java (LTS) 2.73.6) and before BC FIPS TLS Java 1.0.19. When endpoint identification is enabled in the BCJSSE and an SSL socket is created without an explicit hostname (as happens with HttpsURLConnection), hostname verification could be performed against a DNS-resolved IP address in some situations, opening up a possibility of DNS poisoning.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8108-1 advisory.

    It was discovered that Bouncy Castle did not sanitize user input when inserting it into an LDAP search     filter. An attacker could possibly use this issue to perform an LDAP injection attack. This issue only     affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2023-33201)

    It was discovered that Bouncy Castle incorrectly handled specially crafted F2m parameters in the ECCurve     algorithm. An attacker could possibly use this issue to cause Bouncy Castle to use excessive resources,     leading to a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04     LTS, and Ubuntu 24.04 LTS. (CVE-2024-29857)

    It was discovered that Bouncy Castle leaked timing information when handling exceptions during an RSA     handshake. An attacker could possibly use this issue to obtain sensitive information. This issue only     affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2024-30171)

    It was discovered that Bouncy Castle incorrectly handled endpoint identification with an SSL socket     enabled without an explicit hostname. An attacker could possibly use this issue to perform a DNS poisoning     attack. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS.
    (CVE-2024-34447)

    Bing Shi discovered that Bouncy Castle incorrectly handled resource memory allocation. An attacker could     possibly use this issue to cause Bouncy Castle to use excessive resources, leading to a denial of service.
    This issue only affected Ubuntu 24.04 LTS. (CVE-2025-8916)

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

Note that Nessus has not tested for these issues 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.

  - An issue was discovered in the Bouncy Castle Crypto Package For Java before BC TLS Java 1.0.19 (ships with     BC Java 1.78, BC Java (LTS) 2.73.6) and before BC FIPS TLS Java 1.0.19.

(CVE-2024-34447)

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

The 12.2.1.4.0, 14.1.1.0.0, and 14.1.2.0.0 versions of WebLogic Server installed on the remote host are affected by multiple vulnerabilities as referenced in the January 2025 CPU advisory.

  - Easily exploitable vulnerability allows unauthenticated attacker with network access via T3, IIOP to compromise     Oracle WebLogic Server.  Successful attacks of this vulnerability can result in takeover of Oracle WebLogic     Server. (CVE-2024-23635)

  - Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle     WebLogic Server.  While the vulnerability is in Oracle WebLogic Server, attacks may significantly impact additional     products (scope change). Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of Oracle WebLogic Server. (CVE-2023-7272)

  - Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle     WebLogic Server.  Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or     frequently repeatable crash (complete DOS) of Oracle WebLogic Server. (CVE-2024-47554)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-636 advisory.
