Synopsis
=======

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

Background
=========

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

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
net-mail/fetchmail <= 6.2.4 >= 6.2.5

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
=====

Fetchmail users who receive a malicious email may have their fetchmail program crash.

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.

Resolution
=========

Fetchmail users should upgrade to version 6.2.5 or later:

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