Revision History: April 15 2019: An update for SUSE Linux Enterprise Server for SAP 12-SP1 has been released April 8 2019: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- 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] Patch Instructions: To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
