Amazon Linux 2 Security Advisory: ALAS2-2025-3045
Advisory Released Date: 2025-10-27
Advisory Updated Date: 2025-10-27
Squid is a caching proxy for the Web. In Squid versions prior to 7.2, a failure to redact HTTP authentication credentials in error handling allows information disclosure. . 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. The vulnerability is fixed in version 7.2. As a workaround, disable debug information in administrator mailto links generated by Squid by configuring squid.conf with email_err_data off. (CVE-2025-62168)
