|
|
fetchmail is a utility that retrieves and forwards mail from
|
|
remote systems using IMAP, POP, and other protocols.

<description>
|
|
<p>
|
|
fetchmail does not properly validate UIDs coming from a POP3 mail
|
|
server. The UID is placed in a fixed length buffer on the stack, which
|
|
can be overflown.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
Very long UIDs returned from a malicious or compromised POP3
|
|
server can cause fetchmail to crash, resulting in a Denial of Service,
|
|
or allow arbitrary code to be placed on the stack.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There are no known workarounds at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All fetchmail users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-mail/fetchmail-6.2.5.2"</code>
