Amazon Linux AMI : squid (ALAS-2023-1766)

high Nessus Plugin ID 177070

Language:

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 3.5.20-17.48. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1766 advisory.

Incorrect HTTP Request header comparison in Squid HTTP Proxy 3.5.0.1 through 3.5.22, and 4.0.1 through 4.0.16 results in Collapsed Forwarding feature mistakenly identifying some private responses as being suitable for delivery to multiple clients. (CVE-2016-10003)

An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with memory access protections, this can result in the helper process being terminated unexpectedly. This leads to the Squid process also terminating and a denial of service for all clients using the proxy.
(CVE-2020-8517)

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 squid' to update your system.
