Synopsis

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

Description

The version of squid installed on the remote host is prior to 3.5.20-17. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2310 advisory.

- Squid before 4.4 has XSS via a crafted X.509 certificate during HTTP(S) error page generation for certificate errors. (CVE-2018-19131)

- Squid before 4.4, when SNMP is enabled, allows a denial of service (Memory Leak) via an SNMP packet.
(CVE-2018-19132)

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 squid' to update your system.
