Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3392 advisory.

- A DoS vulnerability exists in Rack <v3.0.4.2, <v2.2.6.3, <v2.1.4.3 and <v2.0.9.3 within in the Multipart MIME parsing code in which could allow an attacker to craft requests that can be abuse to cause multipart parsing to take longer than expected. (CVE-2023-27530)

- ooooooo_q reports: Carefully crafted input can cause header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector.
Any applications that parse headers using Rack (virtually all Rails applications) are impacted. (CVE-2023-27539)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ruby-rack packages.

For Debian 10 buster, these problems have been fixed in version 2.0.6-3+deb10u3.
