   An update that fixes 5 vulnerabilities is now available.

Description:

   This update for apache2 fixes the following issues:

   * 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]

   * CVE-2019-0211: A flaw in the Apache HTTP Server allowed less-privileged
     child processes or threads to execute arbitrary code with the privileges
     of the parent process. Attackers with control over CGI scripts or
     extension modules run by the server could have abused this issue to
     potentially gain super user privileges. [bsc#1131233]

   * CVE-2019-0197: When HTTP/2 support was enabled in the Apache server for
     a 'http' host or H2Upgrade was enabled for h2 on a 'https'
 host, an
     Upgrade request from http/1.1 to http/2 that was not the first request
     on a connection could lead to a misconfiguration and crash. This issue
     could have been abused to mount a denial-of-service attack. Servers that
     never enabled the h2 protocol or that only enabled it for https: and did
     not configure the "H2Upgrade on" are unaffected. [bsc#1131245]

   * CVE-2019-0196: Through specially crafted network input the Apache's
     http/2 request handler could be lead to access previously freed memory
     while determining the method of a request. This resulted in the request
     being misclassified and thus being processed incorrectly. [bsc#1131237]
