Description Jan Lieskovsky 2013-01-23 17:02:59 UTC
+++ This bug was initially created as a clone of Bug #903293 +++

Description of problem:
As noted in bug #894626 and in:
  [1] http://www.openwall.com/lists/oss-security/2013/01/23/7

haproxy previously failed to drop supplementary groups properly when trying to drop root privileges.

By itself this problem is not a security flaw, but still serious enough the upstream fix:
  [2] git.1wt.eu/web?p=haproxy.git;a=commitdiff;h=ab012dd3

to be backported into all of the affected versions.

Version-Release number of selected component (if applicable):
haproxy-1.4.22-4.el6op

How reproducible:
Always

Steps to Reproduce:
1. See https://bugzilla.redhat.com/show_bug.cgi?id=894626#c0 for further reproducer details
  
Actual results:
Supplementary groups are not dropped properly after setuid / setgid calls.

Expected results:
(All) Supplementary groups should be dropped when dropping root privileges.

Comment 5 Rory Thrasher 2017-01-13 22:34:30 UTC
OpenShift Enterprise v2 has officially reached EoL.  This product is no longer supported and bugs will be closed.

Please look into the replacement enterprise-grade container option, OpenShift Container Platform v3.  https://www.openshift.com/container-platform/
