Vulnerabilities in H.323 implementations

The NISCC and the OUSPG
developed a test suite for the H.323 protocol. This test
suite has uncovered vulnerabilities in several H.323
implementations with impacts ranging from denial-of-service
to arbitrary code execution.
In the FreeBSD Ports Collection, pwlib' is directly affected. Other applications such as asterisk’ and
openh323' incorporate pwlib’ statically and so are also
independently affected.
