execution of arbitrary code.
Background
==========
Balsa is a highly configurable email client for GNOME.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

Description
===========
Evil Ninja Squirrel discovered a stack-based buffer overflow in the
ir_fetch_seq() function when receiving a long response to a FETCH
command (CVE-2007-5007).
Impact
======
A remote attacker could entice a user to connect to a malicious or
compromised IMAP server, possibly leading to the execution of arbitrary
code with the rights of the user running Balsa.
Workaround
==========
There is no known workaround at this time.
Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/balsa-2.3.20"
