|
|
Stefan Esser discovered errors with evidence of memory corruption in
|
|
the code parsing the headers. Several independent researchers also
|
|
reported errors involving the handling of HTTP headers, the mod_auth
|
|
and mod_scgi modules, and the limitation of active connections.

<impact type="normal">
|
|
<p>
|
|
A remote attacker can trigger any of these vulnerabilities by sending
|
|
malicious data to the server, which may lead to a crash or memory
|
|
exhaustion, and potentially the execution of arbitrary code.
|
|
Additionally, access-deny settings can be evaded by appending a final /
|
|
to a URL.
|
|

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Lighttpd users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.16"</code>
