How to Fix CVE-2019-9512

To remediate this vulnerability, upgrade all affected Golang.org/x/net dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

golang.org/x/net fixed: 0.0.0-20190813141303-74dc4d7220e7
Upgrade golang.org/x/net to 0.0.0-20190813141303-74dc4d7220e7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for golang.org/x/net

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-9512, inspect your project dependencies for Golang.org/x/net:

inspect dependencies for golang.org/x/net

Analyze the terminal output to locate any version of Golang.org/x/net in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.0-20190813141303-74dc4d7220e7), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Golang.org/x/net, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. ### Specific Go Packages Affected golang.org/x/net/http2
