Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 / 25.10 : Erlang vulnerabilities (USN-7831-1)

high Nessus Plugin ID 271189

Synopsis

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

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7831-1 advisory.

It was discovered that Erlang incorrectly handled resource allocation and consumption in the SFTP SSH module. An attacker could possibly use this issue cause Erlang to consume excessive resources, 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 these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
