Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Information Exposure. If all headers were not written out in the first write() call then the code that handles flushing the buffer would always write out the full contents of the writevBuffer buffer, which might contain data from previous requests.
