<background>
|
|
<p>bsdiff and bspatch are tools for building and applying patches to binary
|
|
files.

|
<description>
|
|
<p>It was discovered that the implementation of bspatch did not check for a
|
|
negative value on numbers of bytes read from the diff and extra streams.
|

</description>
|
|
<impact type="high">
|
|
<p>A remote attacker could entice a user to apply a specially crafted patch
|
|
using bspatch, possibly resulting in execution of arbitrary code with the
|
|
privileges of the process or a Denial of Service condition.
|
|
</p>

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

<code>
|

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-util/bsdiff-4.3-r4"
