fetchmail - null pointer dereference

Matthias Andree discovered that fetchmail, an SSL enabled POP3, APOP
and IMAP mail gatherer/forwarder, can under certain circumstances
attempt to dereference a NULL pointer and crash.

For the old stable distribution (sarge), this problem was not present.

For the stable distribution (etch), this problem has been fixed in
version 6.3.6-1etch1.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your fetchmail package.
