Arch Linux Security Advisory ASA-202012-3 ========================================= Severity: Medium Date : 2020-12-05 CVE-ID : CVE-2020-17527 Package : tomcat9 Type : information disclosure Remote : Yes Link : https://security.archlinux.org/AVG-1317 Summary ======= The package tomcat9 before version 9.0.40-1 is vulnerable to information disclosure. Resolution ========== Upgrade to 9.0.40-1. # pacman -Syu "tomcat9>=9.0.40-1" The problem has been fixed upstream in version 9.0.40. Workaround ========== None. Description =========== It was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests. Impact ====== A remote attacker might be able to access sensitive information via well-timed HTTP/2 requests.
