Mandriva Linux Security Update Advisory
_______________________________________________________________________

Package name: wget
Advisory ID: MDKSA-2005:183
Date: October 13th, 2005

Affected versions: 2006.0
______________________________________________________________________

Problem Description:

A vulnerability in libcurl's NTLM function can overflow a stack-based
buffer if given too long a user name or domain name in NTLM
authentication is enabled and either a) pass a user and domain name to
libcurl that together are longer than 192 bytes or b) allow (lib)curl
to follow HTTP redirects and the new URL contains a URL with a user and
domain name that together are longer than 192 bytes.

Wget, as of version 1.10, uses the NTLM code from libcurl and is also
vulnerable to this issue.

The updated packages have been patched to address this issue.
