How to Fix CVE-2020-29244

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

github.com/dhowden/tag fixed: 0.0.0-20201120070457-d52dcb253c63 
Upgrade github.com/dhowden/tag to 0.0.0-20201120070457-d52dcb253c63
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/dhowden/tag

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-29244, inspect your project dependencies for Github.com/dhowden/tag:

inspect dependencies for github.com/dhowden/tag

Analyze the terminal output to locate any version of Github.com/dhowden/tag in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.0-20201120070457-d52dcb253c63), 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-129: Improper Validation of Array Index, where the product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. In Github.com/dhowden/tag, 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

Due to improper bounds checking, a number of methods in dhowden tag before 0.0.0-20201120070457-d52dcb253c63 can trigger a panic due to attempted out-of-bounds reads. If the package is used to parse user supplied input, this may be used as a vector for a denial of service attack.
