critical Nessus Plugin ID 173118

Language:

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-114 advisory.

A flaw was found in the Curl package, where the HSTS mechanism would be ignored by subsequent transfers when done on the same command line because the state would not be properly carried. This issue may result in limited confidentiality and integrity. (CVE-2023-23914)

A flaw was found in the Curl package, where the HSTS mechanism could fail when multiple transfers are done in parallel, as the HSTS cache file gets overwritten by the most recently completed transfer. This issue may result in limited confidentiality and integrity. (CVE-2023-23915)

curl: HTTP multi-header compression denial of service (CVE-2023-23916)

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 'dnf update curl --releasever=2023.0.20230222 ' to update your system.
