(RHSA-2008:0235) Important: speex security update

Speex is a patent-free compression format designed especially for speech.
The Speex package contains a library for handling Speex files and sample
encoder and decoder implementations using this library.

The Speex library was found to not properly validate input values read from
the Speex files headers. An attacker could create a malicious Speex file
that would crash an application or, possibly, allow arbitrary code
execution with the privileges of the application calling the Speex library.
(CVE-2008-1686)

All users of speex are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.
