Vulnerability Details
CVEID: CVE-2019-12206
DESCRIPTION: NGINX njs is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the nxt_utf8_encode function in nxt/nxt_utf8.c. By sending overly long data, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/161279 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

CVSS Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
DESCRIPTION: Kubernetes kubelet could allow a local attacker to gain elevated privileges on the system, caused by an issue with running the container with root in the second run. An attacker could exploit this vulnerability to obtain root access in a container.
CVSS Base Score: 4.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/161858 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L
DESCRIPTION: Docker could allow a local authenticated attacker to gain elevated privileges on the system, caused by a flaw in docker-credential-secretservice. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code in the context of the application.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/173371 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: Undefined
DESCRIPTION: Docker could allow a local authenticated attacker to gain elevated privileges on the system, caused by a flaw in docker-credential-helpers. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code in the context of the application.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/173370 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: Undefined
DESCRIPTION: NGINX could allow a remote attacker to obtain sensitive information, caused by a flaw in certain error_page configurations. By sending a specially crafted request, a remote attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/174252 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
DESCRIPTION: The Kubernetes API server is vulnerable to a denial of service, caused by a billion laughs attack, caused by an error when parsing YAML manifests. A remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/168618 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
DESCRIPTION: Kubernetes kube-state-metrics could allow a remote attacker to obtain sensitive information, caused by a flaw in the experimental feature that enabled annotations to be exposed as metrics. By sending a specially-crafted request, an attacker could exploit this vulnerability to expose the secret content in metrics.
CVSS Base Score: 5.9
