CVE-2025-59362: n/a
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.
AI Analysis
Technical Summary
CVE-2025-59362 describes a vulnerability in Squid through version 7.1 where the ASN.1 encoding of long SNMP Object Identifiers (OIDs) is mishandled in the asn_build_objid function located in lib/snmplib/asn1.c. This improper handling can cause a denial of service condition by crashing the application. The vulnerability is classified under CWE-121 (Stack-based Buffer Overflow). The CVSS v3.1 base score is 4.0, reflecting a local attack vector with low complexity, no privileges required, no user interaction, unchanged scope, and impact limited to availability.
Potential Impact
The vulnerability can cause a denial of service (application crash) when processing specially crafted long SNMP OIDs due to improper ASN.1 encoding handling. There is no impact on confidentiality or integrity. No known exploits are reported in the wild.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. 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.
