The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.6 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1777054556 advisory.

 - An issue was discovered in Squid 4.9 through 4.17 and 5.0.6 through 5.6. Due to inconsistent handling of internal URIs, there can be Exposure of Sensitive Information about clients using the proxy via an HTTPS request to an internal cache manager URL. This is fixed in 5.7. (CVE-2022-41317)

 - Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Affected versions of squid are subject to a a Use-After-Free bug which can lead to a Denial of Service attack via collapsed forwarding.
 All versions of Squid from 3.5 up to and including 5.9 configured with collapsed_forwarding on are vulnerable. Configurations with collapsed_forwarding off or without a collapsed_forwarding directive are not vulnerable. This bug is fixed by Squid version 6.0.1. Users are advised to upgrade. Users unable to upgrade should remove all collapsed_forwarding lines from their squid.conf. (CVE-2023-49288)

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