Description

A memory leak that could be triggered remotely was discovered in ypserv 2.5 and earlier. This could lead to a Denial of Service as repeated requests for a non-existent map will result in ypserv consuming more and more memory, and also running more slowly. If the system runs out of available memory, ypserv would also be killed.
