Hi,

The following vulnerability was published for erlang.

CVE-2025-32433[0]:
| Erlang/OTP is a set of libraries for the Erlang programming
| language. Prior to versions OTP-27.3.3, OTP-26.2.5.11, and
| OTP-25.3.2.20, 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. This issue is patched in
| versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20. A temporary
| workaround involves disabling the SSH server or to prevent access
| via firewall rules.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
