<p>
|
|
mu-b from Digital Labs discovered that the return value of a snprintf()
|
|
call is not properly checked before being used. This could lead to an
|
|
integer overflow.

|
<impact type="high">
|
|
<p>
|
|
A remote attacker could send specially crafted BGP packets on a network
|
|
being monitored with tcpdump, possibly resulting in the execution of
|
|
arbitrary code with the privileges of the user running tcpdump, which
|
|
is usually root.

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All tcpdump users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-3.9.5-r3"</code>
