Description

This security bulletin contains information about 8 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2023-21827)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote authenticated user to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Oracle Database Data Redaction in Oracle Database Server. A remote authenticated user can exploit this vulnerability to gain access to sensitive information.


2) Buffer overflow (CVE-ID: CVE-2018-25032)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when compressing data. A remote attacker can pass specially crafted input to the application, trigger memory corruption and perform a denial of service (DoS) attack.


3) Type conversion (CVE-ID: CVE-2020-10735)

CWE-ID: CWE-704 - Type conversion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a type confusion in algorithms with quadratic time complexity when using non-binary bases within the int() call. A remote attacker can pass specially crafted data to the affected application and perform a denial of service (DoS) attack.


4) Improper input validation (CVE-ID: CVE-2022-39429)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote authenticated user to perform service disruption.

The vulnerability exists due to improper input validation within the Java VM in Oracle Database Server. A remote authenticated user can exploit this vulnerability to perform service disruption.


5) Improper input validation (CVE-ID: CVE-2023-21829)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote authenticated user to read and manipulate data.

The vulnerability exists due to improper input validation within the Oracle Database RDBMS Security in Oracle Database Server. A remote authenticated user can exploit this vulnerability to read and manipulate data.


6) Deserialization of Untrusted Data (CVE-ID: CVE-2022-42003)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insecure input validation when processing serialized data when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. A remote attacker can pass specially crafted data to the application and cause a denial of service condition on the target system.


7) Infinite loop (CVE-ID: CVE-2021-3737)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop. A remote attacker who controls a malicious server can force the client to enter an infinite loop on a 100 Continue response.


8) Improper Certificate Validation (CVE-ID: CVE-2023-21893)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to improper certificate validation within the ValidateRemoteCertificate function in the Oracle ODP.NET managed driver. A remote attacker can perform MitM attack.
