# 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. This vulnerability has been assigned the CVE identifier CVE-2024-26146. Versions Affected: All. 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.

## ASA-2024-004: Default configuration param for Evidence may limit window of validity **Component**: CometBFT **Criticality**: Low **Affected versions**: All **Affected users**: Validators, Chain Builders + Maintainers ## Summary A default configuration in CometBFT has been found to be small for common use cases, and may prevent the slashing mechanism from working in specific cases. The default values for `EvidenceParams.MaxAgeNumBlocks` and `EvidenceParams.MaxAgeDuration` consensus parameters may not be sufficient for common use cases to provide coverage for the entire unbonding period for a chain (`Staking.UnbondingTime`). If the conditions of both of these parameters are exceeded, evidence may be prematurely expired and considered no longer valid, potentially allowing for unpunished Byzantine behavior if evidence is discovered outside of that window. ## Next Steps for Chains and Validators It is recommended that chain ecosystems and their maintainers set the consensus paramet...
