Impact

A remote attacker could entice a user to download a specially-crafted file with an application linked against libwww-perl, which could result in overwritten files or arbitrary code execution by writing to a dotfile in the user’s home directory (such as .bashrc). Additionally, a remote attacker could perform a Man-in-the-Middle attack.

Workaround
