Summary
A ReDoS issue was discovered in the URI component before version 0.12.2 for Ruby. The URI parser mishandles invalid URLs with specific characters, leading to increased execution time when parsing strings to URI objects.
Risk Assessment
Organizations may be vulnerable to DoS attacks that could lead to application slowdowns or unavailability. The increased processing time may affect the performance of systems utilizing this component.
Recommendation
It is recommended to upgrade to version 0.12.2 or 0.10.3, which contain fixes for this vulnerability. Additionally, applications should be monitored for invalid URLs.
