    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.
