|
Robert Buchholz of the Gentoo Security team discovered that the
|
|
flac_buffer_copy() function does not correctly handle FLAC streams with
|
|
variable block sizes which leads to a heap-based buffer overflow
|
|
(CVE-2007-4974).
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could exploit this vulnerability by enticing a user
|
|
to open a specially crafted FLAC file or network stream with an
|
|
application using libsndfile. This might lead to the execution of
|
|
arbitrary code with privileges of the user playing the file.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All libsndfile users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/libsndfile-1.0.17-r1"</code>
