<background>
|
|
<p>libuv is a multi-platform support library with a focus on asynchronous
|
|
I/O.

|
<description>
|
|
<p>It was discovered that libuv does not call setgroups before calling
|
|
setuid/setgid. If this is not called, then even though the uid has been
|
|
dropped, there may still be groups associated that permit superuser
|
|
privileges.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>Context-dependent attackers could escalate privileges via unspecified
|
|
vectors.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All libuv users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --verbose --oneshot ">=dev-libs/libuv-1.4.2"
|

</code>
