(Gentoo Issues Fix) Ringtone Tools Buffer Overflow in parse_emelody() Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1013438
SecurityTracker URL:  http://securitytracker.com/id/1013438
CVE Reference:   CVE-2004-1292   (Links to External Site)
Date:  Mar 16 2005
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 2.22
Description:   A vulnerability was reported in Ringtone Tools. A remote user can cause arbitrary code to be executed by the target user.

D. J. Bernstein reported that a remote user can create a specially crafted eMelody file that, when processed by the target user with Ringtone Tools, will execute arbitrary code on the target user's system. The code will run with the privileges of the target user.

The buffer overflow resides in the parse_emelody() function in 'parse_emelody.c'.

Qiao Zhang is credited with discovering this flaw.

Impact:   A remote user can cause arbitrary code to be executed by the target user with the privileges of the target user.
Solution:   Gentoo has released a fix and indicates that all Ringtone Tools users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-misc/ringtonetools-2.23"

Vendor URL:  ringtonetools.mikekohn.net/ (Links to External Site)
Cause:   Boundary error
Underlying OS:  Linux (Gentoo)

potentially leading to the execution of arbitrary code.

Background
==========

Ringtone Tools is a program for creating ringtones and logos for mobile
phones.

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

Description
===========

Qiao Zhang has discovered a buffer overflow vulnerability in the
'parse_emelody' function in 'parse_emelody.c'.

Impact
