    Several vulnerabilities were discovered in the Erlang/OTP implementation     of the SSH protocol, which may result in denial of service or the     execution of arbitrary code.

    For the stable distribution (bookworm), these problems have been fixed in     version 1:25.2.3+dfsg-1+deb12u1.

    We recommend that you upgrade your erlang packages.

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-7313-1 advisory.

    It was discovered that Erlang incorrectly handled SFTP packet sizes. A remote attacker could possibly use     this issue to cause Erlang to consume resources, resulting in a denial of service.

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

  - Erlang is a programming language and runtime system for building massively scalable soft real-time systems     with requirements on high availability. OTP is a set of Erlang libraries, which consists of the Erlang     runtime system, a number of ready-to-use components mainly written in Erlang. Packet size is not verified     properly for SFTP packets. As a result when multiple SSH packets (conforming to max SSH packet size) are     received by ssh, they might be combined into an SFTP packet which will exceed the max allowed packet size     and potentially cause large amount of memory to be allocated. Note that situation described above can only     happen for successfully authenticated users after completing the SSH handshake. This issue has been     patched in OTP versions 27.2.4, 26.2.5.9, and 25.3.2.18. There are no known workarounds for this     vulnerability. (CVE-2025-26618)

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

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-2025-26618 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.

        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.
