DSA-4332-1 ruby2.3 -- security update
- Date Reported:
- 03 Nov 2018
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2018-16395, CVE-2018-16396.
- More information:
Several vulnerabilities have been discovered in the interpreter for the Ruby language. The Common Vulnerabilities and Exposures project identifies the following problems:
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.
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.
