   An update that fixes three vulnerabilities is now available.

Description:

   This update for apache2 fixes the following issues:

   - CVE-2018-17199: A bug in Apache's "mod_session_cookie" lead to an issue
     where the module did not respect a cookie's expiry time. [bsc#1122839]

   * CVE-2019-0220: The Apache HTTP server did not use a consistent strategy
     for URL normalization throughout all of its components. In particular,
     consecutive slashes were not always collapsed. Attackers could
     potentially abuse these inconsistencies to by-pass access control
     mechanisms and thus gain unauthorized access to protected parts of the
     service. [bsc#1131241]

   * CVE-2019-0217: A race condition in Apache's "mod_auth_digest" when
     running in a threaded server could have allowed users with valid
     credentials to authenticate using another username, bypassing configured
     access control restrictions. [bsc#1131239]
