MDKSA-2002:078-Updated ypserv packages fix memory leak

by Nikola Strahija on November 20th, 2002 Affected versions: 7.2, 8.0, 8.1, 8.2, 9.0


Problem 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-existant 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.
