Description Mark J. Cox 2002-09-30 08:53:40 UTC
Fetchmail is a remote mail retrieval and forwarding utility intended for
use over on-demand TCP/IP links, like SLIP or PPP connections.  Two bugs
have been found in the header parsing code in versions of Fetchmail prior
to 6.1.0.  

The first bug allows a remote attacker to remotely crash Fetchmail by
sending a carefully crafted DNS packet.   The second bug allows a remote
attacker to carefully craft an email in such a way that when it is parsed
by Fetchmail a heap overflow occurs, allowing remote arbitrary code execution.

Both of these bugs are only exploitable if Fetchmail is being used in
multidrop mode (using the "multiple-local-recipients" feature).
