Design/Logic Flaw

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. Virtio ring descriptors, and the data they describe are in a region of memory accessible by from both the virtual machine and the host. An attacker in a VM can change the contents of the memory after vhostcrypto has validate...

Buffer overflow

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A lack of bounds checking when copying ivdata from the VM guest memory into host memory can lead to a large buffer overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as syst...

Design/Logic Flaw

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. 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...

CVE-2020-14374

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A flawed bounds checking in the copydata function leads to a buffer overflow allowing an attacker in a virtual machine to write arbitrary data to any address in the vhostcrypto application. The highest threat from this...

CVE-2020-14374

CVE-2020-14374 affects DPDPDK prior to 18.11.10 and prior to 19.11.5. A flawed bounds check in the copy_data function enables a buffer overflow, letting a VM attacker write arbitrary data to any address in the vhost_crypto component. Impact: data confidentiality, integrity, and availability of th...

CVE-2020-14374

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A flawed bounds checking in the copydata function leads to a buffer overflow allowing an attacker in a virtual machine to write arbitrary data to any address in the vhostcrypto application. The highest threat from this...

CVE-2020-14377

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. 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...

CVE-2020-14377

CVE-2020-14377 is described as a flaw in dpdk prior to 18.11.10 and before 19.11.5 where attacker-controlled parameters are not validated, causing a buffer over-read whose results can be written back into guest memory. This enables a VM-based attacker to read significant host memory, impacting da...

CVE-2020-14375

CVE-2020-14374 to CVE-2020-14378 affect dpdk before 18.11.10 and before 19.11.5. The issues enable memory corruption/over-reads in vhost_crypto paths and related bounds checks (copy_data, move_desc, and Virtio ring descriptors). In a VM, an attacker can read/write host memory, impacting confident...

Moderate: Red Hat Security Advisory: Red Hat Virtualization security and bug fix update
