OpenSSL is used by IBM Robotic Process Automation as part of the API Server (CVE-2022-4304, CVE-2022-4450, CVE-2023-0215, CVE-2023-0286). Golang Go is used by IBM Robotic Process Automation as part of the operator (CVE-2022-32149). Mozilla Network Services is used by IBM Robotic Process Automation as part of Watson NLP (CVE-2023-0767). cURL libcurl is used by IBM Robotic Process Automation as part of container base images (CVE-2023-23916). The vulnerabilities have been addressed.

Vulnerability Details

**CVEID:**CVE-2022-4304 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a timing-based side channel in the RSA Decryption implementation. By sending an overly large number of trial messages for decryption, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246612 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)

**CVEID:**CVE-2022-4450 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a double-free error related to the improper handling of specific PEM data by the PEM_read_bio_ex() function. By sending specially crafted PEM files for parsing, a remote attacker could exploit this vulnerability to cause the system to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246615 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-2022-32149 DESCRIPTION: Golang Go is vulnerable to a denial of service, caused by improper input validation by the golang.org/x/text/language package. By sending a specially-crafted Accept-Language header, a remote attacker could exploit this vulnerability to cause ParseAcceptLanguage to take significant time to parse, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/238605 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-2023-0215 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a use-after-free error related to the incorrect handling of streaming ASN.1 data by the BIO_new_NDEF function. 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/246614 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-2023-0286 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a type confusion error related to X.400 address processing inside an X.509 GeneralName. By passing arbitrary pointers to a memcmp call, a remote attacker could exploit this vulnerability to read memory contents or cause a denial of service.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246611 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H)

**CVEID:**CVE-2023-0767 DESCRIPTION: Mozilla Network Security Services (NSS), as used in Mozilla Firefox, could allow a remote attacker to execute arbitrary code on the system, caused by an arbitrary memory write. By constructing a PKCS 12 cert bundle in such a way, a remote attacker could exploit this vulnerability using PKCS 12 Safe Bag attributes to allow for arbitrary memory writes and execute arbitrary code on the vulnerable system.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/247260 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

**CVEID:**CVE-2023-23916 DESCRIPTION: cURL libcurl is vulnerable to a denial of service, caused by a flaw in the decompression chain implementation. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause memory errors, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/247437 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)
