It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-578 advisory.

    Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to a Buffer Overread bug     Squid is vulnerable to a Denial of Service attack against Squid HTTP Message processing. This bug is fixed     by Squid version 6.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.
    (CVE-2023-49285)

    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)

    SQUID-2023:2 Multiple issues in HTTP response caching (CVE-2023-5824)

    Squid is a caching proxy for the Web. Due to an expired pointer reference bug, Squid prior to version 6.6     is vulnerable to a Denial of Service attack against Cache Manager error responses. This problem allows a     trusted client to perform Denial of Service when generating error pages for Client Manager reports. Squid     older than 5.0.5 have not been tested and should be assumed to be vulnerable. All Squid-5.x up to and     including 5.9 are vulnerable. All Squid-6.x up to and including 6.5 are vulnerable. This bug is fixed by     Squid version 6.6. In addition, patches addressing this problem for the stable releases can be found in     Squid's patch archives. As a workaround, prevent access to Cache Manager using Squid's main access     control: `http_access deny manager`. (CVE-2024-23638)

    Squid is a web proxy cache. Starting in version 3.5.27 and prior to version 6.8, Squid may be vulnerable     to a Denial of Service attack against HTTP Chunked decoder due to an uncontrolled recursion bug. This     problem allows a remote attacker to cause Denial of Service when sending a crafted, chunked, encoded HTTP     Message. This bug is fixed in Squid version 6.8. In addition, patches addressing this problem for the     stable releases can be found in Squid's patch archives. There is no workaround for this issue.
