Package name:           wget
Advisory ID:            MDKSA-2002:086
Date:                   December 11th, 2002

Problem Description:

 A vulnerability in all versions of wget prior to and including 1.8.2
 was discovered by Steven M. Christey.  The bug permits a malicious
 FTP server to create or overwriet files anywhere on the local file
 system by sending filenames beginning with "/" or containing "/../".
 This can be used to make vulnerable FTP clients write files that can
 later be used for attack against the client machine.
