Description

A remote overflow exists in wget. The 'ntlm_output()' function fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted HTTP redirect request containing an overly long NTLM username, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.
