Ubuntu 22.04 LTS / 24.04 LTS / 25.04 : Erlang vulnerabilities (USN-7656-1)

medium Nessus Plugin ID 242577

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7656-1 advisory.

 It was discovered that Erlang OTPs SSH module incorrectly enforced strict KEX handshake hardening measures. A remote attacker able to intercept communications could possibly use this issue to insert optional messages into connections during the handshake. (CVE-2025-46712)

 It was discovered that Erlang OTP incorrectly handled ZIP archives. If a user or automated system were tricked into opening a specially crafted ZIP archive, a remote attacker could possibly use this issue to overwrite arbitrary files outside of the intended directory. (CVE-2025-4748)

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.

Solution

Update the affected packages.
