Amazon Linux AMI : (ALAS-2023-1677)

high Nessus Plugin ID 171045

Language:

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 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 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.
