CVE-2020-17395 (GCVE-0-2020-17395)

Vulnerability from cvelistv5 – Published: 2020-08-25 20:20 – Updated: 2024-08-04 13:53
VLAI
Summary
This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 15.1.4. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the prl_naptd process. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor. Was ZDI-CAN-11134.

CVE-2020-14378 (GCVE-0-2020-14378)

Vulnerability from cvelistv5 – Published: 2020-09-30 00:00 – Updated: 2024-08-04 12:46
VLAI
Summary
An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending on how `vhost_crypto` is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period.
Severity
No CVSS data available.
