Synopsis
=======

rxvt-unicode is vulnerable to a buffer overflow that could lead to the execution of arbitrary code.

Background
=========

rxvt-unicode is a clone of the well known terminal emulator rxvt.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

Description
==========

Rob Holland of the Gentoo Linux Security Audit Team discovered that
rxvt-unicode fails to properly check input length.

Impact

Successful exploitation would allow an attacker to execute arbitrary
code with the permissions of the user running rxvt-unicode.

Workaround
