USN-4128-2: Tomcat vulnerabilities

18 September 2019

Several security issues were fixed in Tomcat 9.




It was discovered that the Tomcat 9 SSI printenv command echoed user
provided data without escaping it. An attacker could possibly use this
issue to perform an XSS attack. (CVE-2019-0221)

It was discovered that Tomcat 9 did not address HTTP/2 connection window
exhaustion on write while addressing CVE-2019-0199. An attacker could
possibly use this issue to cause a denial of service. (CVE-2019-10072)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.04
Ubuntu 18.04

In general, a standard system update will make all the necessary changes.
