The squidclamav_check_preview_handler function in squidclamav.c in SquidClamav 5.x before 5.8 and 6.x before 6.7 passes an unescaped URL to a system command call, which allows remote attackers to cause a denial of service (daemon crash) via a URL with certain characters, as demonstrated using %0D or %0A.

Security readout for executives and security teams

SquidClamav versions 5.x before 5.8 and 6.x before 6.7 can crash when handling specially formed URLs. For organizations using SquidClamav with a proxy, this could interrupt malware scanning or proxy-related service availability. The public sources support denial of service, not data theft or code execution. Exposure is likely limited to environments running SquidClamav 5.x or 6.x in front of users or systems that can submit URLs through the proxy scanning path. Treat this as a service-availability issue. Prioritize remediation where SquidClamav supports production proxy traffic, security scanning, or shared internet access. It is less urgent where the component is absent, isolated, or already updated. Mitigation focus: Upgrade SquidClamav to 5.8, 6.7, or later supported releases.; Review SquidClamav vendor guidance and the fixing commit before backporting.; Restrict proxy access to trusted networks while remediation is pending..
