Title:rxvt-unicode: Buffer overflow
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:
