Detail

Several vulnerabilities have been discovered in the interpreter for the Ruby language. The Common Vulnerabilities and Exposures project identifies the following problems:

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.
