Summary

IBM Watson Discovery for IBM Cloud Pak for Data contains a vulnerable version of Go.

Vulnerability Details

CVEID:CVE-2021-33196
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw in the NewReader and OpenReader functions in archive/zip. By persuading a victim to open a specially-crafted archive file, a remote attacker could exploit this vulnerability to cause a panic or an unrecoverable fatal error, and results in a denial of service condition.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/206602 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

CVEID:CVE-2021-33198
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw in the SetString and UnmarshalText methods of math/big.Rat. By sending a specially-crafted input, a remote attacker could exploit this vulnerability to cause a panic or an unrecoverable fatal error, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/206604 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-2021-29923
**DESCRIPTION:**Golang Go could allow a remote attacker to bypass security restrictions, caused by improper consideration for extraneous zero characters at the beginning of an IP address octet. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass access control based on IP addresses.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/207025 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)

CVEID:CVE-2021-31525
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw in net/http. By sending a specially-crafted header to ReadRequest or ReadResponse. Server, Transport, and Client, a remote attacker could exploit this vulnerability to cause a (panic) denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/202709 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-2021-36221
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a race condition upon an ErrAbortHandler abort. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a net/http/httputil ReverseProxy panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/207036 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-2021-33195
**DESCRIPTION:**Golang Go could allow a remote attacker to execute arbitrary code on the system, caused by not following RFC 1035 rules in the LookupCNAME, LookupSRV, LookupMX, LookupNS, and LookupAddr functions in net. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/206601 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2021-34558
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by the failure to properly assert that the type of public key in an X.509 certificate matches the expected type in the crypto/tls package. By persuading a victim to connect to a specially-crafted TLS server, a remote attacker could exploit this vulnerability to cause a TLS client to panic.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/205578 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-2021-33197
**DESCRIPTION:**Golang Go could allow a remote attacker to bypass security restrictions, caused by a flaw in the ReverseProxy in net/http/httputil. By sending a specially-crafted request, an attacker could exploit this vulnerability to drop arbitrary headers, including those set by the ReverseProxy.Director.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/206603 for the current score.
