CVE-2017-15698

Public on 2018-01-31
Modified on 2018-03-08
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.
