It was found that URLResource.getLastModified() in Undertow closes the file descriptors only when they are finalized which can cause file descriptors to exhaust. This leads to a file handler leak.

Google Guava versions 11.0 through 24.1 are vulnerable to unbounded memory allocation in the AtomicDoubleArray class (when serialized with Java serialization) and Compound Ordering class (when serialized with GWT serialization). An attacker could exploit applications that use Guava and deserialize untrusted data to cause a denial of service.
