SUSE Security Update: Security update for apache2
______________________________________________________________________________
Announcement ID: SUSE-SU-2019:0873-1
Rating: important
References: #1131233 #1131237 #1131239 #1131241 #1131245
Cross-References: CVE-2019-0196 CVE-2019-0197 CVE-2019-0211 CVE-2019-0217
CVE-2019-0220
Affected Products:
SUSE Linux Enterprise Module for Server Applications 15
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]
