Descriptions

Squid is an open source caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to Input Validation, Premature Release of Resource During Expected Lifetime, and Missing Release of Resource after Effective Lifetime bugs, Squid is vulnerable to Denial of Service attacks by a trusted server against all clients using the proxy. This bug is fixed in the default build configuration of Squid version 6.10.

A flaw was found in Squid. Due to input validation and resource management issues, a denial of service may be triggered during the processing of certain Edge Side Includes (ESI) response content.

An update for the squid:4 module is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.4 Update Services for SAP Solutions, and Red Hat Enterprise Linux 8.4 Telecommunications Update Service. Issues addressed include a denial of service vulnerability.
