Amazon Linux 2 : docker (ALASDOCKER-2023-031)

critical Nessus Plugin ID 183448

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of docker installed on the remote host is prior to 20.10.25-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2DOCKER-2023-031 advisory.

2024-05-09: CVE-2022-41723 was added to this advisory.

2023-11-29: CVE-2023-24538 was added to this advisory.

2023-10-31: CVE-2023-24540 was added to this advisory.

http2/hpack: avoid quadratic complexity in hpack decoding (CVE-2022-41723)

Templates did not properly consider backticks (`) as Javascript string delimiters, and as such didnot escape them as expected. Backticks are used, since ES6, for JS template literals. If a templatecontained a Go template action within a Javascript template literal, the contents of the action couldbe used to terminate the literal, injecting arbitrary Javascript code into the Go template. (CVE-2023-24538)

html/template: improper handling of JavaScript whitespace.

Not all valid JavaScript whitespace characters were considered to be whitespace. Templates containing whitespace characters outside of the character set \t\n\f\r\u0020\u2028\u2029 in JavaScript contexts that also contain actions may not be properly sanitized during execution. (CVE-2023-24540)

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-39325)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update docker' to update your system.
