GLSA 200504-07: GnomeVFS, libcdaudio: CDDB response overflow

Severity:normal
Title:GnomeVFS, libcdaudio: CDDB response overflow
Date:04/08/2005
Bugs: #84936
ID:200504-07

Synopsis

The GnomeVFS and libcdaudio libraries contain a buffer overflow that can be triggered by a large CDDB response, potentially allowing the execution of arbitrary code.

Background

GnomeVFS is a filesystem abstraction library for the GNOME desktop environment. libcdaudio is a multi-platform CD player development library. They both include code to query CDDB servers to get Audio CD track titles.

Affected packages

Package Vulnerable Unaffected Architecture(s)
gnome-base/gnome-vfs < 2.8.4-r1 >= 2.8.4-r1 All supported architectures
media-libs/libcdaudio < 0.99.10-r1 >= 0.99.10-r1 All supported architectures

Description

Joseph VanAndel has discovered a buffer overflow in Grip when processing large CDDB results (see GLSA 200503-21). The same overflow is present in GnomeVFS and libcdaudio code.

Impact

A malicious CDDB server could cause applications making use of GnomeVFS or libcdaudio libraries to crash, potentially allowing the execution of arbitrary code with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All GnomeVFS users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose gnome-base/gnome-vfs

All libcdaudio users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libcdaudio-0.99.10-r1"
