File Descriptor Leak in Undertow Affects Red Hat Software

CVE-2018-1114

What is CVE-2018-1114?

The vulnerability in Undertow's URLResource.getLastModified() method leads to a situation where file descriptors are not properly managed, causing them to be exhausted over time. This leak occurs as file descriptors are only closed when they are finalized, creating a potential for resource exhaustion. System performance may degrade as services attempt to handle more requests than file descriptors available. It is advised to apply security patches provided by Red Hat to mitigate this issue.
