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.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2021-27116
DESCRIPTION: Beego could allow a local authenticated attacker to gain elevated privileges on the system, caused by link following in profile.go file in the MemProf 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/224900 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-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.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
