Security Bulletin: Multiple vulnerabilities in the Golang language affect IBM Event Streams

Summary

This security vulnerability affects Golang that is used by the IBM Event Streams CLI component

Vulnerability Details

CVEID:CVE-2021-44716
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled memory consumption in the header canonicalization cache in net/http. By sending HTTP/2 requests, a remote attacker could exploit this vulnerability to consume all available memory resources.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216553 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-2021-44717
**DESCRIPTION:**Golang Go could allow a remote attacker to bypass security restrictions, caused by an error in the syscall.ForkExec() interface. By causing the erroneous closing of file descriptor 0 after file-descriptor exhaustion, an attacker could exploit this vulnerability to compromise data integrity and/or confidentiality in a somewhat uncontrolled way in programs linked with and using syscall.ForkExec().
CVSS Base score: 4.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216563 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N)

CVEID:CVE-2022-23772
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a buffer overflow in the Rat.SetString function in math/big. By sending a specially-crafted request, an attacker could exploit this vulnerability to consume large amount of RAM and cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/219442 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-2022-23773
**DESCRIPTION:**An unspecified error with not treating branches with semantic-version names as releases in cmd/go in Golang Go has an unknown impact and attack vector.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/219443 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2022-23806
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw with IsOnCurve function returns true for invalid field elements. By sending a specially-crafted request, an attacker could exploit this vulnerability to causes a panic in ScalarMult, and results in a denial of condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/219444 for the current score.
