Security update for apache2

SUSE Security Update: Security update for apache2
Announcement ID: SUSE-SU-2016:2090-1
Rating: moderate
References: #951692 #970391 #973381 #988488
Affected Products:
  • SUSE Linux Enterprise Server for SAP 12
  • SUSE Linux Enterprise Server 12-LTSS

  • An update that solves one vulnerability and has three fixes is now available.

    Description:


    This update for apache2 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-2016-5387). 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#988488)

    - Ignore SIGINT signal in child processes. This fixes a race condition in
    signals handling when httpd is running on foreground and the user hits
    ctrl+c. (bsc#970391)

    - Don't put the backend in error state (by default) when 500/503 is
    overridden. (bsc#951692)

    - Remove obsolete /usr/share/apache2/rc.apache2 sample script. (bsc#973381)
