Description

Details for this vulnerability have not been published by NIST at this point. Descriptions from software vendor advisories for this issue are provided below.

From VID-F0798A6A-BBDB-11ED-BA99-080027F5FEC9:

Aaron Patterson reports:

The Multipart MIME parsing code in Rack limits the number

of file parts, but does not limit the total number of

parts that can be uploaded. Carefully crafted requests can

abuse this and cause multipart parsing to take longer than

expected.
