You need JavaScript enabled to view it. https://www.debian.org/lts/security/ Markus Koschany October 30, 2023 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : jetty9 Version : 9.4.50-4+deb10u1 CVE ID : CVE-2020-27218 CVE-2023-36478 CVE-2023-44487 Debian Bug : 976211 Two remotely exploitable security vulnerabilities were discovered in Jetty 9, a Java based web server and servlet engine. The HTTP/2 protocol implementation did not sufficiently verify if HPACK header values exceed their size limit. Furthermore the HTTP/2 protocol allowed a denial of service (server resource consumption) because request cancellation can reset many streams quickly. This problem is also known as Rapid Reset Attack. In addition this version also addresses CVE-2020-27218. If GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection, and if an attacker can send a request with a body that is received entirely but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request. For Debian 10 buster, these problems have been fixed in version 9.4.50-4+deb10u1. We recommend that you upgrade your jetty9 packages. For the detailed security status of jetty9 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/source-package/jetty9 Further information about Debian LTS security advisories, how to apply theseupdates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS .
