<description>
<p>
Neil Hoggarth has discovered that when delivering messages to a message
delivery agent by means of the "mda" option, Fetchmail passes a NULL
pointer to the ferror() and fflush() functions when refusing a message.
Isaac Wilcox has discovered numerous means of plain-text password
disclosure due to errors in secure connection establishment.
</p>
</description>
<impact type="normal">
<p>
An attacker could deliver a message via Fetchmail to a message delivery
agent configured to refuse the message, and crash the Fetchmail
process. SMTP and LMTP delivery modes are not affected by this
vulnerability. An attacker could also perform a Man-in-the-Middle
attack, and obtain plain-text authentication credentials of users
connecting to a Fetchmail process.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All fetchmail users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-mail/fetchmail-6.3.6"</code>
</resolution>
