CVE-2024-25126: Debian Linux

High severity, CVSS 7.5. EPSS: 35.4% chance of exploitation in the next 30 days.

Rack is a modular Ruby web server interface. 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 (ReDos 2nd degree polynomial). This vulnerability is patched in 3.0.9.1 and 2.2.8.1.

Affected products

• Debian Debian Linux: version 10.0 only
• Rack Rack: from 0.4, before 2.2.8.1 (fixed in 2.2.8.1); from 3.0.0, before 3.0.9.1 (fixed in 3.0.9.1)
