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.
