Inefficient Regular Expression Complexity
A denial of service vulnerability in the Range header parsing component of Rack versions 1.5.0.beta.1 through 188.8.131.52, 2.1.0 through 184.108.40.206, 2.2.0 through 220.127.116.11, and 3.0.0.beta1 through 3.0.4. A Carefully crafted input can cause the Range header parsing component in Rack to take an unexpected amount of time, possibly resulting in a Denial of Service attack vector. Any applications that deal with Range requests (such as streaming applications, or applications that serve files) may be impacted.
CWE-1333 - Inefficient Regular Expression Complexity
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
