SUSE Security Update: Security update for apache2

______________________________________________________________________________

Announcement ID:   SUSE-SU-2019:0873-1
Rating:            important

                   SUSE Linux Enterprise Module for Open Buildservice Development Tools 15
______________________________________________________________________________

An update that fixes 5 vulnerabilities is now available.

Description:

This update for apache2 fixes the following issues:

  o 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]


  o 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]


  o 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]


  o 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]


  o 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]
