| Package | Affected versions | Patched versions |
|---|---|---|
| org.apache.tomcat:tomcat | ≥ 8.5.0, < 8.5.8≥ 9.0.0.M1, < 9.0.0.M12 | 8.5.89.0.0.M12 |
| tomcat | = 8.5.0= 8.5.1= 8.5.2= 8.5.3= 8.5.4= 8.5.5= 8.5.6= 9.0.0 |
The HTTP/2 header parser in Apache Tomcat 9.0.0.M1 to 9.0.0.M11 and 8.5.0 to 8.5.6 entered an infinite loop if a header was received that was larger than the available buffer. This made a denial of service attack possible.
