FreeBSD : fetchmail -- remote root/code injection from malicious POP3 server (3497d7be-2fef-45f4-8162-9063751b573a)
Medium Nessus Plugin ID 19339
The remote FreeBSD host is missing a security-related update.
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.
