Vulnerability Details

CVEID:CVE-2022-3064
**DESCRIPTION:**Go-Yaml package is vulnerable to a denial of service, caused by an unbounded alias chasing flaw. By using a specially-crafted YAML file, a remote attacker could exploit this vulnerability to consume significant CPU or memory resources.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/243452 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-2021-4235
**DESCRIPTION:**Go-Yaml Yaml Go package is vulnerable to a denial of service, caused by an unbounded alias chasing flaw. By using a specially-crafted YAML file, a remote authenticated attacker could exploit this vulnerability to consume significant system resources, and results in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/243312 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

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-2022-32149
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by improper input validation by the golang.org/x/text/language package. By sending a specially-crafted Accept-Language header, a remote attacker could exploit this vulnerability to cause ParseAcceptLanguage to take significant time to parse, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/238605 for the current score.

CVEID:CVE-2021-27117
**DESCRIPTION:**Beego could allow a local authenticated attacker to gain elevated privileges on the system, caused by link following in the profile.go file in the GetCPUProfile function. An attacker could exploit this vulnerability to launch symlink attacks.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/224898 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-41721
**DESCRIPTION:**Golang Go is vulnerable to HTTP request smuggling, caused by a flaw when using MaxBytesHandler. By sending a specially-crafted HTTP(S) transfer-encoding request header, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/244775 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

CVEID:CVE-2022-41723
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw in the HPACK decoder. By sending a specially-crafted HTTP/2 stream, a remote attacker could exploit this vulnerability to cause excessive CPU consumption, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/247965 for the current score.
