Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 ESM / 23.04 : Docker Registry vulnerabilities (USN-6336-1)

high Nessus Plugin ID 180473

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6336-1 advisory.

 - Docker Registry before 2.6.2 in Docker Distribution does not properly restrict the amount of content accepted from a user, which allows remote attackers to cause a denial of service (memory consumption) via the manifest endpoint. (CVE-2017-11468)

 - A flaw was found in the `/v2/_catalog` endpoint in distribution/distribution, which accepts a parameter to control the maximum number of records returned (query string: `n`). This vulnerability allows a malicious user to submit an unreasonably large value for `n,` causing the allocation of a massive string array, possibly causing a denial of service through excessive use of memory. (CVE-2023-2253)

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 docker-registry package.
