Severity: High Title: pdnsd: Denial of Service and potential arbitrary code execution Date: May 10, 2006 Bugs: #131341 ID: 200605-10

Synopsis ========
pdnsd is vulnerable to a buffer overflow that may result in arbitrary code execution.
Background ==========
pdnsd is a proxy DNS server with permanent caching that is designed to cope with unreachable DNS servers.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dns/pdnsd < 1.2.4 >= 1.2.4
Description ===========
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 ======
An attacker can craft malicious DNS queries leading to a Denial of Service, and potentially the execution of arbitrary code.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All pdnsd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/pdnsd-1.2.4-r1"
