The Xiph.org Free Lossless Audio Codec (FLAC) library is the reference
|
|
implementation of the FLAC audio file format. It contains encoders and
|
|
decoders in library and executable form.

<description>
|
|
<p>
|
|
Sean de Regge reported multiple integer overflows when processing FLAC
|
|
media files that could lead to improper memory allocations resulting in
|
|
heap-based buffer overflows.
|
|
</p>

|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user to open a specially crafted FLAC
|
|
file or network stream with an application using FLAC. 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 FLAC users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/flac-1.2.1-r1"</code>
|
|
<p>
|
|
You should also run revdep-rebuild to rebuild any packages that depend
|
|
on older versions of FLAC:
|
|
</p>
|
|
<code>
|
|
# revdep-rebuild --library=libFLAC.*</code>
|
|
</resolution>
