<p>
Fetchmail versions 6.2.4 and earlier can be crashed by sending a
specially-crafted email to a fetchmail user. This problem occurs because
Fetchmail does not properly allocate memory for long lines in an incoming
email.

Fetchmail users who receive a malicious email may have their fetchmail
program crash.
</p>

<p>
While a workaround is not currently known for this issue, all users are advised to upgrade to the latest version of fetchmail.

</p>
<code>
# emerge sync
# emerge -pv ">=net-mail/fetchmail-6.2.5"
# emerge ">=net-mail/fetchmail-6.2.5"</code>
