Issue Overview:

A Denial of Service (DoS) vulnerability was found in rubygem-rack in how it parses Content-Type. Carefully crafted content type headers can cause Rack’s media type parser to take much longer than expected, leading to a possible denial of service vulnerability. (CVE-2024-25126)

A Denial of Service (DoS) vulnerability was found in rubygem-rack in how it parses Range Header. Carefully crafted Range headers can cause a server to respond with an unexpectedly large response. Responding with such large responses could lead to a denial of service issue. (CVE-2024-26141)

A Denial of Service (DoS) vulnerability was found in rubygem-rack in how it parses Rack Header. Carefully crafted headers can cause header parsing in Rack to take longer than expected resulting in a possible denial of service issue. Accept and Forwarded headers are impacted. (CVE-2024-26146)
