Description Agostino Sarubbo gentoo-dev 2013-02-14 18:43:39 UTC
From ${URL} :

A denial of service flaw was found in the way Pacemaker, an advanced, scalable high-availability cluster resource manager for Linux-HA (Heartbeat) and/or Corosync, 
performed authentication and processing of remote connections in certain circumstances. In general Pacemaker used a blocking socket (without a timeout) to wait for 
authentication credentials to arrive. When Pacemaker was configured to allow remote Cluster Information Base (CIB) cluster's configuration / cluster's resources management, 
a remote attacker could use this flaw to cause Pacemaker to block indefinitely (preventing it from serving another requests).

FYI I'm in discussion with upstream to get a new tag release of pacemaker which would avoid the need to patch this ourselves.

<Ultrabug> meaning, this week ? :p
<beekhof> highly likely

I should be able to fix this soon ;)
Comment 3 Ultrabug gentoo-dev 2013-03-08 17:35:27 UTC
Now 1.1.9 is tagged, builds fine but doesn't work... I'm in contact with upstream about this :(
Comment 4 Ultrabug gentoo-dev 2013-03-13 13:50:03 UTC
+*pacemaker-1.1.9 (13 Mar 2013)
+  13 Mar 2013; Ultrabug <> +pacemaker-1.1.9.ebuild:
+  Version bump fix #457572

NOTE that due to perm issues with newer pacemaker/libqb ACL support, you now need to add root to the haclient group if pacemaker is compiled with USE acl !

Are we okay to stable pacemaker-1.1.10?

By all means, yes !

Arches, please test and mark stable:

@Jeroen: why bug 455418 is a blocker for this?

> @Jeroen: why bug 455418 is a blocker for this?

Because we're being asked to stabilise sys-cluster/libdlm which has the problem pointed out in that bug report.
Comment 10 GLSAMaker/CVETool Bot gentoo-dev 2013-11-27 10:19:04 UTC
CVE-2013-0281 (
  Pacemaker 1.1.10, when remote Cluster Information Base (CIB) configuration
  or resource management is enabled, does not limit the duration of
  connections to the blocking sockets, which allows remote attackers to cause
  a denial of service (connection blocking).
Comment 11 Agostino Sarubbo gentoo-dev 2013-12-23 13:25:33 UTC
CC back the arch teams when it is ready
Comment 12 Ultrabug gentoo-dev 2015-03-23 11:16:15 UTC
All fixed, please proceed with related stabilization.

I'll drop all 1.0.x versions afterwards.
