Red Hat Security Advisory: delve security update
Delve is a debugger for the Go programming language. The goal of the project is to provide a simple, full featured debugging tool for Go. Delve should be easy to invoke and easy to use. Chances are if you're using a debugger, things aren't going your way. With that in mind, Delve should stay out of your way as much as possible. Security Fix(es): * crypto/x509: golang: Denial of Service due to excessive resource consumption via crafted certificate (CVE-2025-61729) * golang: net/url: Memory exhaustion in query parameter parsing in net/url (CVE-2025-61726) * crypto/tls: Unexpected session resumption in crypto/tls (CVE-2025-68121) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
