Improper Locking in Apache Tomcat
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.apache.tomcat.embed:tomcat-embed-core | >= 9.0.0.M1, < 9.0.20 | 9.0.20 |
| Maven | org.apache.tomcat.embed:tomcat-embed-core | >= 8.5.0, < 8.5.41 | 8.5.41 |
Details
As written in the advisory (Markdown source, shown as plain text).
The fix for CVE-2019-0199 was incomplete and did not address HTTP/2 connection window exhaustion on write in Apache Tomcat versions 9.0.0.M1 to 9.0.19 and 8.5.0 to 8.5.40 . By not sending WINDOW_UPDATE messages for the connection window (stream 0) clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS.
