CVE-2017-15698

tomcat-native: Mishandling of client certificates can allow for OCSP check bypass

Published Jan 31, 2018 CVSS 3.0 · 5.9 Medium EPSS 3.5% KEV · Not listed
Description
When parsing the AIA-Extension field of a client certificate, Apache Tomcat Native Connector 1.2.0 to 1.2.14 and 1.1.23 to 1.1.34 did not correctly handle fields longer than 127 bytes. The result of the parsing error was to skip the OCSP check. It was therefore possible for client certificates that should have been rejected (if the OCSP check had been made) to be accepted. Users not using OCSP checks are not affected by this vulnerability.
