+ <title>Fetchmail: Denial of Service and password disclosure</title>
+ <synopsis>
+ Fetchmail has been found to have numerous vulnerabilities allowing for
+ Denial of Service and password disclosure.
+ </synopsis>

+ <affected>
+ <package name="net-mail/fetchmail" auto="yes" arch="*">
+ <unaffected range="ge">6.3.6</unaffected>
+ <vulnerable range="lt">6.3.6</vulnerable>
+ </package>
+ </affected>
+ <background>
+ <p>
+ Fetchmail is a remote mail retrieval and forwarding utility.
+ </p>
+ </background>
+ <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>
