<background>
|
|
<p>Xdelta is a C library and command-line tool for delta compression using
|
|
VCDIFF/RFC 3284 streams.

<description>
|
|
<p>A buffer overflow can be triggered within xdelta when ran against a
|
|
malicious input file.

</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>A remote attacker could coerce the victim to run xdelta against a
|
|
malicious input file. This may be leveraged by an attacker to crash
|
|
xdelta and gain control of program execution.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All xdelta users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-util/xdelta-3.0.10"
|
