An update of the erlang package has been released.

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by a vulnerability as referenced in the USN-7425-1 advisory.

    It was discovered that Erlang OTP's SSH module did not limit the size of certain data in initialization     messages. An attacker could possibly use this issue to consume large amount of memory leading to a denial     of service.

Tenable has extracted the preceding description block directly from the Ubuntu 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 version of erlang 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-2025-30211 advisory.

  - Erlang/OTP is a set of libraries for the Erlang programming language. Prior to versions OTP-27.3.1,     26.2.5.10, and 25.3.2.19, a maliciously formed KEX init message can result with high memory usage.
    Implementation does not verify RFC specified limits on algorithm names (64 characters) provided in KEX     init message. Big KEX init packet May lead to inefficient processing of the error data. As a result, large     amount of memory will be allocated for processing malicious data. Versions OTP-27.3.1, OTP-26.2.5.10, and     OTP-25.3.2.19 fix the issue. Some workarounds are available. One May set option `parallel_login` to     `false` and/or reduce the `max_sessions` option. (CVE-2025-30211)

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

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:1356-1 advisory.

    - CVE-2025-30211: Fixed KEX init error results with excessive memory usage (bsc#1240390)
     - CVE-2025-32433: Fixed unauthenticated remote code execution in Erlang/OTP SSH (bsc#1241300)

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

The version of erlang installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-30211 advisory.

    Multiple vulnerabilties were fixed in erlang.

    CVE-2023-48795 (Terrapin attack)

        The SSH transport protocol with certain OpenSSH extensions,         allows remote attackers to bypass integrity checks such         that some packets are omitted (from the extension         negotiation message), and a client and server may         consequently end up with a connection for which         some security features have been downgraded.

    CVE-2025-26618

        The SSH transport protocol with certain OpenSSH extensions,         allows remote attackers to bypass integrity checks such         that some packets are omitted (from the extension         negotiation message), and a client and server may         consequently end up with a connection for which         some security features have been downgraded.

    CVE-2025-32433

        A SSH server may allow an attacker to perform unauthenticated         remote code execution (RCE). By exploiting a flaw in SSH protocol         message handling, a malicious actor could gain unauthorized access         to affected systems and execute arbitrary commands without valid         credentials.

    For Debian 11 bullseye, these problems have been fixed in version     1:23.2.6+dfsg-1+deb11u2.

    We recommend that you upgrade your erlang packages.
