Software-update: Racket 6.9

Door , 0 reacties, submitter: begintmeta, bron: Racket

Racket is een ontwikkeltaal waarmee andere ontwikkeltalen ontwikkeld kunnen worden. Daarnaast kan er ook gewoon in Racket zelf ontwikkeld worden. Het stond eerder bekend onder de naam PLT Scheme en komt uit de Lisp-Scheme-familie. Voor de achtergrond verwijzen we naar het manifesto, geschreven onder leiding van Matthias Felleisen. De ontwikkelaars hebben enkele dagen geleden versie 6.9 van Racket uitgebracht, met de volgende aankondiging:

Racket v6.9

Security Announcement
A security vulnerability in the racket/sandbox library and Typed Racket allowed malicious Typed Racket code to escape the sandbox. This vulnerability has been fixed in Racket version 6.9. Anyone using racket/sandbox to execute untrustworthy code with access to Typed Racket should upgrade to version 6.9 immediately. While this known vulnerability has been eliminated, it is possible that similar errors in other installed collections could also be exploited, although we are not currently aware of any existing vulnerabilities. We recommend that if you use the Racket sandbox to execute untrustworthy Racket code, you should also employ additional operating system or virtual machine level protections. The documentation for racket/sandbox has been updated to list recommended security practices for using the library. Thanks to Scott Moore for identifying this vulnerability.
  • The official package catalog Web site is revised to have a new user experience.
  • The Northwestern snapshot site keeps weekly snapshots going up to 12 weeks into the past. Those provide a middle ground for users who want access to new features earlier than stable releases, but want less churn than nightly builds.
  • DrRacket provides a refactoring tool to remove unused requires in modules.
  • DrRacket’s #lang-line customization support works better with buggy (i.e., in development) languages.
  • The web server’s cookie libraries, including “id cookie” authentication, support RFC 6265.
  • The db library supports PostgreSQL’s UUID type.
  • The raco command lists matching commands when passed an ambiguous command prefix.
  • The bytecode compiler detects more optimization opportunities for structure operations.
  • Scribble can produce output via XeLaTeX as an alternative to LaTeX.
  • Scribble supports the acmart LaTeX style, for use with ACM publications.
  • Scribble supports the use of CJK characters in tags.
