Summary

Important: delve security update

Details

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.

CVE-2025-68121 (GCVE-0-2025-68121)

Vulnerability from cvelistv5 – Published: 2026-02-05 17:48 – Updated: 2026-02-20 16:05

Title

Unexpected session resumption in crypto/tls

Summary

During session resumption in crypto/tls, if the underlying Config has its ClientCAs or RootCAs fields mutated between the initial handshake and the resumed handshake, the resumed handshake may succeed when it should have failed. This may happen when a user calls Config.Clone and mutates the returned Config, or uses Config.GetConfigForClient. This can cause a client to resume a session with a server that it would not have resumed with during the initial handshake, or cause a server to resume a session with a client that it would not have resumed with during the initial handshake.

Severity ?

7.4 (High)

CVE-2025-61726 (GCVE-0-2025-61726)

Vulnerability from cvelistv5 – Published: 2026-01-28 19:30 – Updated: 2026-01-29 18:31

Title

Memory exhaustion in query parameter parsing in net/url

Summary

The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption.

Severity ?

7.5 (High)

CVE-2025-61729 (GCVE-0-2025-61729)

Vulnerability from cvelistv5 – Published: 2025-12-02 18:54 – Updated: 2025-12-03 19:37

Title

Excessive resource consumption when printing error string for host certificate validation in crypto/x509

Summary

Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption.

Severity ?

7.5 (High)
