Debian Security Advisory DSA-4332-1 [email protected]

Package : ruby2.3
CVE ID : CVE-2018-16395 CVE-2018-16396

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.

For the detailed security status of ruby2.3 please refer to its security
tracker page at:
