Security Bulletin: Vulnerabilities in Golang Go, MinIO, and Python may affect IBM Spectrum Protect Plus Container Backup and Restore for Kubernetes and OpenShift

Summary

Vulnerabilities in Golang Go, MinIO, and Python such as denial of service, elevated privilegs, and bypass of security restrictions, may affect IBM Spectrum Protect Plus Container backup and restore for Kubernetes and OpenShift

Vulnerability Details

CVEID:CVE-2021-3737
**DESCRIPTION:**Python is vulnerable to a denial of service, caused by improper handling of HTTP response in the HTTP client code. By persuading a victim to visit a specially-crafted web site, a remote attacker could exploit this vulnerability to cause the client script enter an infinite loop, and results in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213407 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

CVEID:CVE-2021-41772
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an out-of-bounds slice situation in the Reader.Open function. By using a specially-crafted ZIP archive containing an invalid name or an empty filename field, a remote attacker could exploit this vulnerability to cause a panic, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213019 for the current score.

CVEID:CVE-2021-41771
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an out-of-bounds slice situation in the ImportedSymbols function in debug/macho. By using specially-crafted binaries, a remote attacker could exploit this vulnerability to cause a panic, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213016 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-2021-43858
**DESCRIPTION:**MinIO could allow a remote attacker to gain elevated privileges on the system, caused by a flaw in the AddUser() admin API. By sending a specially-crafted HTTP API call, an attacker could exploit this vulnerability to update Policy for a user and gain elevated privileges.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216226 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

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-2021-3733
**DESCRIPTION:**Python is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw in the AbstractBasicAuthHandler class in urllib. By persuading a victim to visit a specially-crafted web site, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213034 for the current score.
