Summary
Crass: Non-ASCII characters cause superlinear CPU consumption
Details

Crass is a Ruby CSS parser that's fully compliant with the CSS Syntax Level 3 specification. Prior to 1.0.7, when Crass parses input containing non-ASCII characters, inefficiencies in tracking the positions of multi-byte characters result in superlinear parsing time. An attacker-controlled CSS input consisting of many non-ASCII characters can therefore cause excessive CPU consumption and potentially denial of service. This issue is fixed in version 1.0.7.
