fetchmail’s POP3/UIDL code does not truncate received UIDs properly.
A malicious or compromised POP3 server can thus corrupt fetchmail’s
stack and inject code when fetchmail is using UIDL, either through
configuration, or as a result of certain server capabilities. Note
that fetchmail is run as root on some sites, so an attack might
compromise the root account and thus the whole machine.
