Integer Overflow vulnerability in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2, allows attackers to cause a denial of service (DoS) via mbedtls_x509_set_extension().

The remote Ubuntu 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-8123-1 advisory.

    It was discovered that Mbed TLS incorrectly handled memory allocation failures. A remote attacker could     possibly use this issue to crash the program. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04     LTS. (CVE-2021-44732)

    Jonathan Winzig discovered that Mbed TLS incorrectly handled crafted inputs. A remote attacker could     possibly use this issue to crash the program, resulting in a denial of service. This issue only affected     Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS. (CVE-2024-23775)

    It was discovered that Mbed TLS incorrectly handled the TLS handshake. A remote attacker could possibly     use this issue to break the security guarantees of the TLS handshake. (CVE-2025-27810)

    Linh Le and Ngan Nguyen discovered that Mbed TLS incorrectly documented the behavior of a function.
    Application code relying on the documented behavior might be affected. A remote attacker could possibly     use this issue to execute arbitrary code. (CVE-2025-47917)

    Linh Le and Ngan Nguyen discovered that Mbed TLS incorrectly handled crafted input. A remote attacker     could possibly use this issue to crash the program, resulting in a denial of service. (CVE-2025-48965)

    It was discovered that Mbed TLS incorrectly handled a race condition. An attacker could possibly use this     issue to extract AES keys. (CVE-2025-52496)

    Linh Le and Ngan Nguyen discovered that Mbed TLS incorrectly handled certain invalid input. A remote     attacker could possibly use this issue to crash the program, resulting in a denial of service.
    (CVE-2025-52497)

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.

  - Integer Overflow vulnerability in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2, allows attackers to     cause a denial of service (DoS) via mbedtls_x509_set_extension(). (CVE-2024-23775)

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

The version of hvloader installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-23775 advisory.
