Description

An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous value of the heap. This may expose possibly sensitive data from the interpreter.

Ruby

ChocolateyRuby is a dynamic, open source programming language focusing on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. This package provides a self-contained [Windows-based installer](https://rubyinstaller.org) that includes the Ruby language, an execution environment, important documentation, and more. ## Package Parameters - `/InstallDir` - Ruby installation directory, by default `c:\tools\RubyXY` where XY are major and minor version parts. - `/NoPath` - Do not add ruby bin folder to machine PATH. Example: `choco install ruby --package-parameters="'/NoPath ""/InstallDir:C:\your\install\path""'"` ## Notes - To install ruby development kit ruby installer provides `ridk` command. It provides an easy way to install msys2 via `ridk install 1`, however, the installation is interactive. To accomplish unattended install, use [msys2](https://chocolatey.org/packages/msys2) package.
