Security Bulletin: IBM Cloud Pak System is vulnerable to multiple vulnerabilities in Golang Go

Summary

Cloud Pak System is vulnerable to multiple vulnerabilities in Golang Go. The fix removes these vulnerablities in IBM Cloud Pak System.

Vulnerability Details

CVEID:CVE-2022-32148
**DESCRIPTION:**Golang Go could allow a remote attacker to obtain sensitive information, caused by improper exposure of client IP addresses in net/http. By calling httputil.ReverseProxy.ServeHTTP with a Request.Header map containing a nil value for the X-Forwarded-For header, an attacker could exploit this vulnerability to obtain the client IP address information, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233148 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-2022-29804
**DESCRIPTION:**Golang Go could allow a local attacker to bypass security restrictions, caused by a flaw in the filepath.Clean function. By sending a specially-crafted request, an attacker could exploit this vulnerability to convert an invalid path to a valid, absolute path.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229857 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)

CVEID:CVE-2022-30632
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Glob in path/filepath due to stack exhaustion. By sending a specially-crafted request using a path containing a large number of path separators, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233145 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-2022-30633
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Unmarshal in encoding/xml due to stack exhaustion. By parsing a specially-crafted XML document, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233146 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-2022-30629
**DESCRIPTION:**Golang Go could allow a remote attacker to obtain sensitive information, caused by an issue with session tickets generated by crypto/tls did not contain a randomly generated ticket_age_add. By comparing ticket ages during session resumption, an attacker could exploit this vulnerability to observe TLS handshakes information to correlate successive connections.
CVSS Base score: 7.5

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2022-1962
**DESCRIPTION:*Golang Go is vulnerable to a denial of service, caused by a stack exhaustion flaw in all Parse functions. By sending a specially-crafted request, a local attacker could exploit this vulnerability to cause a panic, and results in a denial of service condition.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/232543 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-27664
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw in net/http. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a closing HTTP/2 server connection to hang, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235355 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-2022-28131
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Decoder.Skip in encoding/xml due to stack exhaustion. By parsing a specially-crafted XML document, a remote attacker could exploit this vulnerability to cause a panic.
