[GLSA]

Gentoo Linux Security Advisory

Title: GnomeVFS, libcdaudio: CDDB response overflow (GLSA 200504-07)
Severity: normal
Exploitable: remote
Date: April 08, 2005
Updated: April 13, 2005
Bug(s): #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: gnome-base/gnome-vfs
Vulnerable: < 2.8.4-r1
Unaffected: >= 2.8.4-r1
Unaffected: >= 1.0.5-r4 < 1.0.6
Architectures: All supported architectures

Package: media-libs/libcdaudio
Vulnerable: < 0.99.10-r1
Unaffected: >= 0.99.10-r1
Architectures: 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:
