Synopsis

========

 

Improper input validation in Speex might lead to array indexing

vulnerabilities in multiple player applications.

 

Background

==========

 

Speex is an audio compression format designed for speech that is free

of patent restrictions.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 media-libs/speex < 1.2_beta3_p2 >= 1.2_beta3_p2

 

Description

===========

 

oCERT reported that the Speex library does not properly validate the

"mode" value it derives from Speex streams, allowing for array indexing

vulnerabilities inside multiple player applications. Within Gentoo,

xine-lib, VLC, gst-plugins-speex from the GStreamer Good Plug-ins,

vorbis-tools, libfishsound, Sweep, SDL_sound, and speexdec were found

to be vulnerable.

 

Impact

======

 

A remote attacker could entice a user to open a specially crafted Speex

file or network stream with an application listed above. This might

lead to the execution of arbitrary code with privileges of the user

playing the file.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All Speex users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=media-libs/speex-1.2_beta3_p2"
