Synopsis
=======

Fetchmail versions 6.2.4 and earlier can be crashed by sending a specially-crafted email to a fetchmail user.



Background

Affected packages
================

-------------------------------------------------------------------

Description
==========

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.

Impact

Workaround
=========

While a workaround is not currently known for this issue, all users are advised to upgrade to the latest version of the affected package.
