Synopsis

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

Description

The version of squid installed on the remote host is prior to 3.5.20-17.55. It is, therefore, affected by a vulnerability as referenced in the ALAS-2024-1933 advisory.

Due to chunked decoder lenience Squid is vulnerable to Request/Response smuggling attacks when parsing HTTP/1.1 and ICAP messages. (CVE-2023-46846)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update squid' to update your system.
