Crass : Large numeric exponents cause CPU and memory denial of service

影響: rubygems:crass < 1.0.7 → 1.0.7

Crass converts CSS scientific notation number values with unbounded exponentiation before it clamps the result to Float::MAX. Applications that use Crass to parse attacker-controlled CSS strings can be forced to spend disproportionate CPU and memory parsing a tiny input, possibly resulting in a crash. Patches This is fixed in Crass 1.0.7. Related - https://github.com/rubysec/ruby-advisory-db/blob/master/gems/crass/GHSA-6wmf-3r64-vcwv.yml
