Improper Restriction of Operations within the Bounds of a Memory Buffer in Apache Tomcat

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...

Improper Limitation of a Pathname to a Restricted Directory in Apache Tomcat

The Mapper component in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.30, and 9.x before 9.0.0.M2 processes redirects before considering security constraints and Filters, which allows remote attackers to determine the existence of a directory via a URL that lacks a trailing /...

Concurrent Execution using Shared Resource with Improper Synchronization in Apache Tomcat

A bug in the error handling of the send file code for the NIO HTTP connector in Apache Tomcat 9.0.0.M1 to 9.0.0.M13, 8.5.0 to 8.5.8, 8.0.0.RC1 to 8.0.39, 7.0.0 to 7.0.73 and 6.0.16 to 6.0.48 resulted in the current Processor object being added to the Processor cache multiple times. This in turn...
