Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1677 advisory.

In Squid 3.x through 3.5.28, 4.x through 4.17, and 5.x before 5.6, due to improper buffer management, a Denial of Service can occur when processing long Gopher server responses. (CVE-2021-46784)

A flaw was found in Squid. An incorrect integer overflow protection in the Squid SSPI and SMB authentication helpers is vulnerable to a buffer overflow attack, resulting in information disclosure or a denial of service. (CVE-2022-41318)

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

pkg_manager = 'yum'Run ' update squid' to update your system.
