What to do
AI-suggested
Users should monitor vendor advisories for updates. Until a fix is released, limiting local access to the affected Squid service and avoiding processing untrusted SNMP data may reduce risk.
Description
Squid versions up to and including 7.1 contain a vulnerability in the ASN.1 encoding handling of long SNMP OIDs within the asn_build_objid function in lib/snmplib/asn1.c. This flaw can lead to an application crash or denial of service. The vulnerability has a medium severity rating and does not impact confidentiality or integrity, only availability.
