How to Fix CVE-2015-3900
To remediate this vulnerability, upgrade all affected Rubygems update dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade rubygems-update to 2.0.16Upgrade rubygems-update to 2.2.4Upgrade rubygems-update to 2.4.7Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for rubygems-updateHow to Check if You Are Affected
To determine whether your application is affected by CVE-2015-3900, inspect your project dependencies for Rubygems update:
inspect dependencies for rubygems-updateAnalyze the terminal output to locate any version of Rubygems update in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.16), 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-350: Reliance on Reverse DNS Resolution for a Security-Critical Action, where the product performs reverse dns resolution on an ip address to obtain the hostname and make a security decision, but it does not properly ensure that the ip address is truly associated with the hostname. In Rubygems update, 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.
