| Doc Text: |
A flaw was found in dpdk. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability.

Description

Statement: This flaw does not affect the versions of `dpdk` as shipped with Red Hat Enterprise Linux 7 and 8 or the versions embedded in Red Hat Virtualization or the Fast Datapath `openvswitch` package, as they do not enable generic crypto device library support. This causes the vulnerable code in vhost_crypto.c to not be included. This flaw does not affect Red Hat Ceph Storage 3 and 4 as dpdk (embedded in ceph source rpm) is not built in the packages, therefore the vulnerable code is not available in the resulting RPM and the issue cannot be exploited. Acknowledgments: Name: Ryan Hall External References: https://www.openwall.com/lists/oss-security/2020/09/28/3 Created dpdk tracking bugs for this issue: Affects: fedora-all [bug 1883276] This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2020-14377 |
