CVE-2011-0534
Apache Tomcat 7.0.0 through 7.0.6 and 6.0.0 through 6.0.30 does not enforce the maxHttpHeaderSize limit for requests involving the NIO HTTP connector, which allows remote attackers to cause a denial of service (OutOfMemoryError) via a crafted request.

Does this matter?
Lower severity and a low EPSS score (7.89%). Track it; it rarely justifies an emergency change on its own.
