Vulnerability Details

CVEID:CVE-2019-11254
**DESCRIPTION:**Kubernetes is vulnerable to a denial of service, caused by a flaw in kube-apiserver. By sending a specially-crafted request using YAML payloads, a remote authenticated attacker could exploit this vulnerability to consume excessive CPU cycles.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/178935 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-8565
**DESCRIPTION:**Kubernetes could allow a local authenticated attacker to obtain sensitive information, caused by a flaw when kube-apiserver is using logLevel >= 9. By gaining access to the log files, an attacker could exploit this vulnerability to obtain the Kubernetes authorization tokens information, and use this information to launch further attacks against the affected system.
CVSS Base score: 4.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/189925 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2020-14040
**DESCRIPTION:**Go Language x/text package is vulnerable to a denial of service, caused by a vulnerability in encoding/unicode in the UTF-16 decoder. By sending a single byte to a UTF16 decoder, a remote attacker could exploit this vulnerability to cause the application to enter into an infinite loop.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/184313 for the current score.
