This update of ruby provides 1.8.7p357, which contains many stability fixes and bug fixes while maintaining full compatibility with the previous version. A detailailed list of changes is available from http://svn.ruby-lang.org/repos/ruby/tags/v1_8_7_357/ChangeLog .

The most important fixes are :

  • Hash functions are now using a randomized seed to avoid algorithmic complexity attacks. If available, OpenSSL::Random.seed at the SecureRandom.random_bytes is used to achieve this. (CVE-2011-4815)

  • mkconfig.rb: fix for continued lines.

  • Fix Infinity to be greater than any bignum number.

  • Initialize store->ex_data.sk.

  • Several IPv6 related fixes.

  • Fixes for zlib.

  • Reinitialize PRNG when forking children. (CVE-2011-2686 / CVE-2011-3009)

  • Fixes to securerandom. (CVE-2011-2705)

  • Fix uri route_to

  • Fix race condition with variables and autoload.
