Debian: DSA-4332-1 Critical: Ruby2.3 Certificate Threat

CVE-2018-16395

Tyler Eckstein reported that the equality check of
OpenSSL::X509::Name could return true for non-equal objects. If a
malicious X.509 certificate is passed to compare with an existing
certificate, there is a possibility to be judged incorrectly that
they are equal.

CVE-2018-16396

Chris Seaton discovered that tainted flags are not propagated in
Array#pack and String#unpack with some directives.

For the stable distribution (stretch), these problems have been fixed in
version 2.3.3-1+deb9u4.

We recommend that you upgrade your ruby2.3 packages.
