Upgrade github.com/cloudflare/cfrpki to 1.4.4
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 github.com/cloudflare/cfrpki

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-3616, inspect your project dependencies for Github.com/cloudflare/cfrpki:

inspect dependencies for github.com/cloudflare/cfrpki

Analyze the terminal output to locate any version of Github.com/cloudflare/cfrpki in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.4), 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-834: Excessive Iteration, where the product performs an iteration or loop without sufficiently limiting the number of times that the loop is executed. In Github.com/cloudflare/cfrpki, 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

### Impact Attackers can create long chains of CAs that would lead to OctoRPKI exceeding its max iterations parameter. In consequence it would cause the program to crash, preventing it from finishing the validation and leading to a denial of service. Credits to Donika Mirdita and Haya Shulman - Fraunhofer SIT, ATHENE, who discovered and reported this vulnerability. ### Specific Go Packages Affected github.com/cloudflare/cfrpki/cmd/octorpki ### Patches This issue is fixed in v1.4.4 ### Workarounds None.
