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

0.0.1 - 1.0.6
Summary
Crass : Large numeric exponents cause CPU and memory denial of service
Details
Impact
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.
