<description>
|
|
<p>Multiple integer overflow errors in libevent could cause a heap-based
|
|
buffer overflow.

|
|
<impact type="normal">
|
|
<p>A context-dependent attacker could cause an application linked against
|
|
libevent to pass an excessively long input through evbuffer, possibly
|
|
resulting in execution of arbitrary code with the privileges of the
|
|
process or a Denial of Service condition.

</impact>

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

<code>

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/libevent-2.0.22"
