Severity:	normal
Title:	DUMB: Heap buffer overflow
Date:	08/08/2006
Bugs:	#142387
ID:	200608-14

Synopsis

A heap-based buffer overflow in DUMB could result in the execution of arbitrary code.

Background

DUMB (Dynamic Universal Music Bibliotheque) is an IT, XM, S3M and MOD player library.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/dumb	< 0.9.3-r1	>= 0.9.3-r1	All supported architectures

Description

Luigi Auriemma found a heap-based buffer overflow in the it_read_envelope function which reads the envelope values for volume, pan and pitch of the instruments referenced in a ".it" (Impulse Tracker) file with a large number of nodes.

Impact

By enticing a user to load a malicious ".it" (Impulse Tracker) file, an attacker may execute arbitrary code with the rights of the user running the application that uses a vulnerable DUMB library.

Workaround

There is no known workaround at this time.

Resolution

All users of DUMB should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/dumb-0.9.3-r1"
