<title>Ethereal: Buffer overflow in OSPF protocol dissector</title>
|
|
<synopsis>
|
|
Ethereal is missing bounds checking in the OSPF protocol dissector that
|
|

|
|
code.

Ethereal is a feature-rich network protocol analyzer. It provides
|
|
protocol analyzers for various network flows, including one for Open
|
|
Shortest Path First (OSPF) Interior Gateway Protocol.

<description>
|
|
<p>
|
|
iDEFENSE reported a possible overflow due to the lack of bounds
|
|
checking in the dissect_ospf_v3_address_prefix() function, part of the
|
|
OSPF protocol dissector.
|

|
<impact type="high">
|
|
<p>
|
|
An attacker might be able to craft a malicious network flow that
|
|
would crash Ethereal. It may be possible, though unlikely, to exploit
|
|
this flaw to execute arbitrary code with the permissions of the user
|
|
running Ethereal, which could be the root user.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Ethereal users should upgrade to the latest version:

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.13-r2"</code>
