|
|
The pdnsd team has discovered an unspecified buffer overflow
|
|
vulnerability. The PROTOS DNS Test Suite, by the Oulu University Secure
|
|
Programming Group (OUSPG), has also revealed a memory leak error within
|
|
the handling of the QTYPE and QCLASS DNS queries, leading to
|
|
consumption of large amounts of memory.

|
<impact type="high">
|
|
<p>
|
|
An attacker can craft malicious DNS queries leading to a Denial of
|
|
Service, and potentially the execution of arbitrary code.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</workaround>
|
|
<resolution>
|
|
<p>
|
|
All pdnsd users should upgrade to the latest version:
|

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-dns/pdnsd-1.2.4-r1"</code>
