Description Laura Pardo 2018-06-19 14:33:25 UTC
A flaw was found in Redis before 5.0. A type confusion in the xgroupCommand function in t_stream.c in redis-server allows remote attackers to cause denial-of-service via an XGROUP command in which the key is not a stream.

Comment 1 Laura Pardo 2018-06-19 14:34:06 UTC
Created redis tracking bugs for this issue:

Affects: epel-all [bug 1592893]
Affects: fedora-all [bug 1592895]

Comment 3 Summer Long 2018-06-20 03:08:54 UTC
The Streams implementation was first committed in 5.0-rc1: https://github.com/antirez/redis/tree/5.0-rc1/src
This fix is for 5.0-rc3. The flawed code is not in earlier versions; openstack uses at the latest, redis-3.2.8-2.el7ost
Setting all openstack to notaffected.

Comment 4 Nathan Scott 2018-06-20 08:38:45 UTC
This code (t_stream.c) is part of the not-yet-released-upstream redis-5 series - its still in beta upstream, is not released, and is not in any Red Hat product.
