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]
