CVE-2018-16470 [HIGH] CVE-2018-16470 rubygem-rack: Buffer size in multipart parser allows for denial of service
CVE-2018-16470 rubygem-rack: Buffer size in multipart parser allows for denial of service
Rack (rubygem-rack) versions 2.04 and 2.0.5 are vulnerable to a denial of service due to incorrect buffer size in the multipart parser. Carefully crafted requests can cause the multipart parser to enter a pathological state, causing the parser to use CPU resources disproportionate to the request size.
