Vulnerability Details

CVEID:CVE-2023-0217
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference related to the validation of certain DSA public keys. A remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246619 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-2023-1255
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a flaw in the AES-XTS cipher decryption implementation for 64 bit ARM platform. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/253370 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2023-0401
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference during PKCS7 data verification. A remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246618 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-2023-0216
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by an invalid pointer dereference related to the incorrect handling of malformed PKCS7 data. A remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246617 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-2022-4203
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a read buffer overrun triggered by the improper handling of X.509 certificate verification. 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/246613 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-2022-3358
**DESCRIPTION:**OpenSSL could allow a remote attacker to obtain sensitive information, caused by the improper handling of legacy custom ciphers passed to the EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() functions. By creating a custom cipher with NID_undef using the legacy EVP_CIPHER_meth_new()function, a remote attacker could exploit this vulnerability force the use of a NULL cipher and emit the plaintext as the ciphertext.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/238264 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

Affected Products and Versions

Remediation/Fixes

IBM strongly suggests the following:
App Connect Enterprise Certified Container 6.2.0 (Continuous Delivery)

Upgrade to App Connect Enterprise Certified Container Operator version 7.0.0 or higher, and ensure that all Dashboard components are at 12.0.7.0-r2 or higher. Documentation on the upgrade process is available at <https://www.ibm.com/docs/en/app-connect/containers_cd?topic=releases-upgrading-operator&gt;
