Description Alexandros Toptsoglou 2018-12-19 16:45:23 UTC 
CVE-2018-20125

A Null pointer dereference issue was found in QEMU's implementation of 
VMWare's paravirtual RDMA device. It could occur while creating CQ/QP ring 
objects in pvrdma_ring_init() routine. A guest user/process could use this flaw to crash QEMU process or allocate excessive memory on host resulting in DoS.

Fix added to qemu package about to be submitted to openSUSE:Factory and SLE15-SP1. No other qemu packages we ship are affected.
