crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries

A flaw was found in the crypto/x509 package of golang. This vulnerability allows a remote attacker to cause a Denial of Service DoS by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name SAN entries. The certificate verification process, specifical...

Security Bulletin: TS4500 CLI tool addresses security vulnerability CVE-2026-16107

Summary The TS4500 CLI tool used an insecure SSL configuration that did not properly validate server certificates, potentially allowing attackers to intercept communications through a Man-in-the-Middle MitM attack. The issue has been resolved by enforcing proper SSL certificate validation during...

GHSA-J92G-9F8W-J867 PostgreSQL JDBC Driver: Silent channel-binding authentication downgrade via unsupported certificate algorithms

Impact channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to guarantee. An attacker who can intercept the TLS connection triggers the downgrade...
