Summary

Apache Tomcat before 6.0.39, 7.0.50, and 8.0.0-RC10 processes chunked transfer coding without properly handling large amounts of chunked data or whitespace characters in HTTP header values within trailer fields, allowing remote attackers to cause a denial of service by streaming data. This vulnerability exists due to an incomplete fix for CVE-2012-3544.

Risk Assessment

An attacker could cause server overload and service unavailability, leading to application downtime.

Recommendation

Upgrade Apache Tomcat to version 6.0.39, 7.0.50, or later (for 8.x to 8.0.0-RC10 or later). Ensure the fix for CVE-2012-3544 is fully applied.
