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: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246612 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

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-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-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-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-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-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-2022-25881
**DESCRIPTION:**Node.js http-cache-semantics module is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw. By sending a specially-crafted regex input using request header values, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246089 for the current score.
