Amazon Linux 2 : squid (ALASSQUID4-2023-001)

high Nessus Plugin ID 181998

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 4.15-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2SQUID4-2023-001 advisory.

- A buffer over-read was discovered in libntlmauth in Squid 2.5 through 5.6. Due to incorrect integer- overflow protection, the SSPI and SMB authentication helpers are vulnerable to reading unintended memory locations. In some configurations, cleartext credentials from these locations are sent to a client. This is fixed in 5.7. (CVE-2022-41318)

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.
