How to Fix CVE-2014-0177

To remediate this vulnerability, upgrade all affected Github.com/github/hub 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/github/hub fixed: 1.12.1 
Upgrade github.com/github/hub to 1.12.1
hub fixed: 1.12.1 
Upgrade hub to 1.12.1
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/github/hub

How to Check if You Are Affected

To determine whether your application is affected by CVE-2014-0177, inspect your project dependencies for Github.com/github/hub:

inspect dependencies for github.com/github/hub

Analyze the terminal output to locate any version of Github.com/github/hub in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.12.1), 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-377: Insecure Temporary File, where creating and using insecure temporary files can leave application and system data vulnerable to attack.
