Subject [UPDATE][SECURITY] CVE-2018-8037 Apache Tomcat - Information Disclosure
Date Thu, 09 Aug 2018 20:00:30 GMT
CVE-2018-8037 Apache Tomcat - Information Disclosure

Severity: Important

Vendor: The Apache Software Foundation

Versions Affected:
Apache Tomcat 9.0.0.M9 to 9.0.9
Apache Tomcat 8.5.5 to 8.5.31

Description:

If an async request was completed by the application at the same time as 
the container triggered the async timeout, a race condition existed that 
could result in a user seeing a response intended for a different user. 
An additional issue was present in the NIO and NIO2 connectors that did 
not correctly track the closure of the connection when an async request 
was completed by the application and timed out by the container at the 
same time. This could also result in a user seeing a response intended 
for another user.

Mitigation:
Users of the affected versions should apply one of the following
mitigations:
- Upgrade to Apache Tomcat 9.0.10 or later.
- Upgrade to Apache Tomcat 8.5.32 or later.
