Package : tomcat8
Version : 8.5.54-0+deb9u8
CVE ID : CVE-2021-41079
Apache Tomcat did not properly validate incoming TLS packets. When Tomcat
was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially
crafted packet could be used to trigger an infinite loop resulting in a
denial of service.
For Debian 9 stretch, this problem has been fixed in version
8.5.54-0+deb9u8.
We recommend that you upgrade your tomcat8 packages.
For the detailed security status of tomcat8 please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/tomcat8
