CVSS v2 Base Score: 4.6 (AV:L/AC:L/Au:N/C:P/I:P/A:P)

ID: CVE-2019-18683

Title: Linux kernel vulnerability in the V4L2 subsystem

Vendor: Multi-Vendor

Description: These vulnerabilities are caused by incorrect mutex locking in the vivid driver of the V4L2 subsystem (drivers/media/platform/vivid). This driver doesn't require any special hardware. It is shipped in Ubuntu, Debian, Arch Linux, SUSE Linux Enterprise, and openSUSE as a kernel module (CONFIG_VIDEO_VIVID=m).

ID: CVE-2020-0601

Title: Microsoft Windows CryptoAPI Spoofing Vulnerability

Vendor: Microsoft

Description: A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates. An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source. The user would have no way of knowing the file was malicious, because the digital signature would appear to be from a trusted provider.

A successful exploit could also allow the attacker to conduct man-in-the-middle attacks and decrypt confidential information on user connections to the affected software.

CVSS v2 Base Score:5.8 (AV:N/AC:M/Au:N/C:N/I:P/A:N)

ID: CVE-2019-19781
