high Nessus Plugin ID 189520

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 23.04 / 23.10 host has a package installed that is affected by a vulnerability as referenced in the USN-6597-1 advisory.

 It was discovered that Puma incorrectly handled parsing chunked transfer encoding bodies. A remote attacker could possibly use this issue to cause Puma to consume 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 this issue but has instead relied only on the application's self-reported version number.
