Security update for libtcnative-1-0

This update for libtcnative-1-0 to version 1.1.34 fixes the following issues:

  • CVE-2017-15698: Fixed an improper handling of fields with more than 127 bytes which could allow invalid client certificates to be accepted (bsc#1078679).
  • CVE-2018-8019: When using an OCSP responder did not correctly handle invalid responses. This allowed for revoked client certificates to be incorrectly identified. It was therefore possible for users to authenticate with revoked certificates when using mutual TLS (bsc#1103348).
  • CVE-2018-8020: Did not properly check OCSP pre-produced responses. Revoked client certificates may have not been properly identified, allowing for users to authenticate with revoked certificates to connections that require mutual TLS (bsc#1103347).

Описание

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.

Описание

When using an OCSP responder Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 did not correctly handle invalid responses. This allowed for revoked client certificates to be incorrectly identified. It was therefore possible for users to authenticate with revoked certificates when using mutual TLS. Users not using OCSP checks are not affected by this vulnerability.

Описание

Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 has a flaw that does not properly check OCSP pre-produced responses, which are lists (multiple entries) of certificate statuses. Subsequently, revoked client certificates may not be properly identified, allowing for users to authenticate with revoked certificates to connections that require mutual TLS. Users not using OCSP checks are not affected by this vulnerability.
