Description

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.

Note that Tenable Network Security has extracted the preceding 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.
