Package : tomcat8
Version : 8.5.54-0+deb9u3
CVE ID : CVE-2020-13934 CVE-2020-13935

Several security vulnerabilities have been discovered in the Tomcat
servlet and JSP engine.

CVE-2020-13934

An h2c direct connection to Apache Tomcat did not release the
HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient
number of such requests were made, an OutOfMemoryException could
occur leading to a denial of service.

CVE-2020-13935

The payload length in a WebSocket frame was not correctly validated
in Apache Tomcat. Invalid payload lengths could trigger an infinite
loop. Multiple requests with invalid payload lengths could lead to a
denial of service.

For Debian 9 stretch, these problems have been fixed in version
8.5.54-0+deb9u3.

We recommend that you upgrade your tomcat8 packages.
