Affected Products:
  • SUSE Linux Enterprise Server for SAP 12-SP1
  • SUSE Linux Enterprise Server 12-SP1-LTSS

An update that fixes two vulnerabilities is now available.

Description:

This update for apache2 fixes the following issues:

Security issues fixed:

  • CVE-2016-8743: Fixed liberal whitespace interpretation accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution. (bsc#1016715)
  • CVE-2016-4975: Fixed possible CRLF injection allowing HTTP response splitting attacks for sites which use mod_userdir. This issue was mitigated by changes which prohibit CR or LF injection into the "Location" or other outbound header key or value. (bsc#1104826)
