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
-------------------------------------------------------------------
1 x11-terms/rxvt-unicode < 5.3 >= 5.3
< 4.8
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
==========
There is no known workaround at this time.
Resolution
==========
All rxvt-unicode users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-terms/rxvt-unicode-5.3"
