Security Advisories 🚨

🚨 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.

🚨 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.

🚨 Denial of Service Vulnerability in Rack Content-Type Parsing

There is a possible denial of service vulnerability in the content type
parsing component of Rack. This vulnerability has been assigned the CVE
identifier CVE-2024-25126.

Versions Affected: >= 0.4 Not affected: < 0.4 Fixed Versions: 3.0.9.1, 2.2.8.1

Impact

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.

Impacted code will use Rack’s media type parser to parse content type headers.
This code will look like below:

request.media_type
OR
request.media_type_params
OR
Rack::MediaType.type(content_type)

Some frameworks (including Rails) call this code internally, so upgrading is
recommended!

All users running an affected release should either upgrade or use one of the
workarounds immediately.

Releases

The fixed releases are available at the normal locations.

Workarounds

There are no feasible workarounds for this issue.
