Uncontrolled Resource Consumption vulnerability in Erlang OTP ssh (ssh_sftp modules) allows Excessive Allocation, Flooding. This vulnerability is associated with program files lib/ssh/src/ssh_sftpd.erl. This issue affects OTP form OTP 17.0 until OTP 28.0.3, OTP 27.3.4.3 and 26.2.5.15 corresponding to ssh from 3.0.1 until 5.3.3, 5.2.11.3 and 5.1.4.12.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20043-1 advisory.

    Update the ssh component to the latest in the maint-27 branch.

    Security issues fixed:

    - CVE-2025-48040: ssh: overly tolerant handling of data received from unauthenticated users when     processing key       exchange messages may lead to excessive resource consumption (bsc#1249472).
    - CVE-2025-48039: ssh: unverified paths from authenticated SFTP users may lead to excessive resource     consumption       (bsc#1249469).
    - CVE-2025-48038: ssh: unverified file handles from authenticated SFTP users may lead to excessive     resource consumption       (bsc#1249470).
