SUSE SLES12 Security Update : apache2 (SUSE-SU-2018:2554-1)

Medium Nessus Plugin ID 112199

Synopsis

The remote SUSE host is missing one or more security updates.

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)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
