+ pdnsd is a proxy DNS server with permanent caching that is
+ designed to cope with unreachable DNS servers.

+ <description>
+ <p>
+ 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.
+ </p>
+ </description>
+ <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.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All pdnsd users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-dns/pdnsd-1.2.4-r1"</code>
