    Squid a popular proxy server was affected by multiple vulnerabilities

    CVE-2025-59362

        Squid mishandles ASN.1 encoding of long SNMP OIDs. This occurs in         asn_build_objid in lib/snmplib/asn1.c.

    CVE-2025-62168

        A failure to redact HTTP authentication credentials in error         handling allows information disclosure. The vulnerability allows a         script to bypass browser security protections and learn the         credentials a trusted client uses to authenticate.
        This potentially allows a remote client to identify security tokens         or credentials used internally by a web application using Squid for         backend load balancing. These attacks do not require Squid to         be configured with HTTP authentication

    For Debian 11 bullseye, these problems have been fixed in version     4.13-10+deb11u6.

    We recommend that you upgrade your squid packages.

The AlmaLinux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1774622460 advisory.

  - Squid is a caching proxy for the Web. Prior to version 7.5, due to improper input validation, Squid is     vulnerable to out of bounds read when handling ICP traffic. This problem allows a remote attacker to     receive small amounts of memory potentially containing sensitive information when responding with errors     to invalid ICP requests. This attack is limited to Squid deployments that explicitly enable ICP support     (i.e. configure non-zero `icp_port`). This problem cannot be mitigated by denying ICP queries using     `icp_access` rules. Version 7.5 contains a patch. (CVE-2026-33515)

  - Squid is a caching proxy for the Web. Prior to version 7.5, due to heap Use-After-Free, Squid is     vulnerable to Denial of Service when handling ICP traffic. This problem allows a remote attacker to     perform a reliable and repeatable Denial of Service attack against the Squid service using ICP protocol.
