Published Sep 14, 2017
·
Updated

It was found that the decode method of the OpenSSL::ASN1 module was vulnerable to buffer underrun. An attacker could pass a specially crafted string to the application in order to crash the ruby interpreter, causing a denial of service.

Other sources

Ruby. Multiple issues in Ruby were addressed in this update.

The decode method in the OpenSSL::ASN1 module in Ruby before 2.2.8, 2.3.x before 2.3.5, and 2.4.x through 2.4.1 allows attackers to cause a denial of service (interpreter crash) via a crafted string. The openssl gem that contains this module is patched in version 2.0.0.

The decode method in the OpenSSL::ASN1 module in Ruby before 2.2.8, 2.3.x before 2.3.5, and 2.4.x through 2.4.1 allows attackers to cause a denial of service (interpreter crash) via a crafted string.

There is a buffer underrun vulnerability in OpenSSL bundled by Ruby. If a malicious string is passed to the decode method of OpenSSL::ASN1, buffer underrun may be caused and the Ruby interpreter may crash.
