<description>
|
|
<p>Integer overflow errors have been discovered in the
|
|
jbig2_decode_symbol_dict, jbig2_build_huffman_table, and
|
|
jbig2_image_compose functions of jbig2dec.

<impact type="normal">
|
|
<p>A remote attacker, by enticing a user to open a specially crafted JBIG2
|
|
file using an application linked against jbig2dec, could possibly execute
|
|
arbitrary code with the privileges of the process or cause a Denial of
|
|
Service condition.

</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All jbig2dec users should upgrade to the latest version:</p>

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/jbig2dec-0.13-r4"
