Affected Products:
  • SUSE Linux Enterprise Software Development Kit 11 SP4

An update that solves one vulnerability can now be installed.

Description:

This update for apache2-mod_fcgid fixes the following issues:

  • It used to be possible to set an arbitrary $HTTP_PROXY environment variable for request handlers -- like CGI scripts -- by including a specially crafted HTTP header in the request (CVE-2016-1000104). As a result, these server components would potentially direct all their outgoing HTTP traffic through a malicious proxy server. This patch fixes the issue: the updated Apache server ignores such HTTP headers and never sets $HTTP_PROXY for sub-processes (unless a value has been explicitly configured by the administrator in the configuration file). (bsc#988492)
