Date:	03/20/2005
Bugs:	#84680
ID:	200503-23

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	Architecture(s)
x11-terms/rxvt-unicode	< 5.3	>= 5.3	All supported architectures

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"
