                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           ypserv
Advisory ID:            MDKSA-2002:078
Date:                   November 18th, 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.
