# Possible DoS Vulnerability with Range Header in Rack There is a possible DoS vulnerability relating to the Range request header in Rack. This vulnerability has been assigned the CVE identifier CVE-2024-26141. Versions Affected: >= 1.3.0. Not affected: < 1.3.0 Fixed Versions: 3.0.9.1, 2.2.8.1 Impact ------ 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. Vulnerable applications will use the `Rack::File` middleware or the `Rack::Utils.byte_ranges` methods (this includes Rails applications). Releases -------- The fixed releases are available at the normal locations. Workarounds ----------- There are no feasible workarounds for this issue. Patches ------- To aid users who aren't able to upgrade immediately we have provided patches for the two supported release series. They are in git-am format and consist of a single changeset. * 3-0-range.pa...
# Possible Denial of Service Vulnerability in Rack Header Parsing There is a possible denial of service vulnerability in the header parsing routines in Rack.

Not affected: None Fixed Versions: 2.0.9.4, 2.1.4.4, 2.2.8.1, 3.0.9.1 Impact ------ 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. Ruby 3.2 has mitigations for this problem, so Rack applications using Ruby 3.2 or newer are unaffected. Releases -------- The fixed releases are available at the normal locations. Workarounds ----------- There are no feasible workarounds for this issue. Patches ------- To aid users who aren't able to upgrade immediately we have provided patches for the two supported release series.
