Dear Ruby and LTS Maintainers, I plan updating the ruby-eventmachine package in Wheezy LTS to fix the following security issue: https://security-tracker.debian.org/tracker/TEMP-0678512-2E167C
Please see the diff to previous version attached. Changes: ruby-eventmachine (0.12.10-3+deb7u1) wheezy-security; urgency=medium . * Fix remotely triggerable crash due to FD handling * Add net-tools to build dependencies to let tests run * Run all tests in tests/ directory The binary packages for amd64 are also available for testing here: https://people.debian.org/~rbalint/ppa/wheezy-lts/wheezy-security/ I plan updating Jessie's version through jessie-proposed-updates, since the issue is marked as no-DSA. Cheers, Balint
