Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

In fetchmail, the remote code injection via POP3 UIDL was
fixed, but a denial of service attack was introduced :

Two possible NULL pointer dereferences allow a malicious POP3 server
to crash fetchmail by respondig with UID lines containing only the
article number but no UID (in violation of RFC-1939), or a message
without Message-ID when no UIDL support is available.
