DPDK iv_data Buffer Overflow Vulnerability

DPDK is a data plane development kit for Linux-based platforms. DPDK ivdata buffer overflow vulnerability. The vulnerability stems from a networked system or product performing operations in memory without properly validating data boundaries, resulting in incorrect read and write operations being...

DEBIAN-CVE-2020-14378

An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the movedesc function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause movedesc to get stuck in a 4,294,967,295-count iteration loop. Depending on how vhostcrypto is...

DEBIAN-CVE-2020-14376

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...

DEBIAN-CVE-2020-14375

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...

dpdk: librte_vhost Integer truncation in vhost_user_check_and_alloc_queue_pair()

A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index a UInt is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption...

USN-4550-1 dpdk vulnerabilities

Ryan Hall discovered that DPDK incorrectly handled vhost crypto. An attacker inside a guest could use these issues to perform multiple attacks, including denial of service attacks, obtaining sensitive information from the host, and possibly executing arbitrary code on the host...

UBUNTU-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...

UBUNTU-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...
