Amazon Linux 2 : golang (ALAS-2023-2313)

critical Nessus Plugin ID 183206

Language:

Synopsis

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

Description

The version of golang installed on the remote host is prior to 1.20.10-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2313 advisory.

2024-01-03: CVE-2023-39319 was added to this advisory.

2023-10-30: CVE-2023-39318 was added to this advisory.

The html/template package does not properly handle HTML-like comment tokens, nor hashbang #! comment tokens, in <script> contexts. This may cause the template parser to improperly interpret the contents of <script> contexts, causing actions to be improperly escaped. This may be leveraged to perform an XSS attack. (CVE-2023-39318)

The html/template package does not apply the proper rules for handling occurrences of <script, <!--, and </script within JS literals in <script> contexts. This may cause the template parser to improperly consider script contexts to be terminated early, causing actions to be improperly escaped. This could be leveraged to perform an XSS attack. (CVE-2023-39319)

Line directives (//line) can be used to bypass the restrictions on //go:cgo_ directives, allowing blocked linker and compiler flags to be passed during compilation. This can result in unexpected execution of arbitrary code when running go build. The line directive requires the absolute path of the file in which the directive lives, which makes exploiting this issue significantly more complex. (CVE-2023-39323)

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 golang' to update your system.
