Security Bulletin: IBM Storage Fusion HCI may be vulnerable to denial of service due to jackson-databind, okio (CVE-2022-42003, CVE-2023-35116, CVE-2023-3635)

Summary

Java libraries jackson-databind and okio are used by IBM Storage Fusion HCI for logging. Vulnerabilities in these libraries could lead to Denial of Service as described the the CVEs listed in the “Vulnerability Details” section.

Vulnerability Details

CVEID:CVE-2022-42003
**DESCRIPTION:**FasterXML jackson-databind is vulnerable to a denial of service, caused by a lack of a check in the primitive value deserializers when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. By sending a specially-crafted request using deep wrapper array nesting, a local attacker could exploit this vulnerability to exhaust all available resources.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/237662 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-2023-35116
**DESCRIPTION:**Fasterxml jackson-databind is vulnerable to a denial of service, caused by a stack-based overflow. By persuading a victim to open a specially crafted content, a remote attacker could exploit this vulnerability to cause a denial of service. Note: The vendor disputes the vulnerability because the steps of constructing a cyclic data structure and trying to serialize it cannot be achieved by an external attacker.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258157 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-2023-3635
**DESCRIPTION:**Okio GzipSource is vulnerable to a denial of service, caused by unhandled exception. By sending a specially crafted gzip buffer, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/260866 for the current score.
