"A buffer overflow has been found in the NTLM authentication handler of
the Curl library and wget. By tricking an user or automatic system
that uses the Curl library, the curl application, or wget into
visiting a specially crafted website, a remote attacker could exploit
this to execute arbitrary code with the privileges of the calling
user.

The Ubuntu 4.10 and 5.04 versions of wget are not affected by this.

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
