Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Improper input validation (CVE-ID: CVE-2024-20995)

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

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

2) Improper input validation (CVE-ID: CVE-2023-36632)

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

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

3) Improper input validation (CVE-ID: CVE-2024-21066)

The vulnerability allows a local privileged user to gain access to sensitive information.

The vulnerability exists due to improper input validation within the RDBMS in Oracle Database Server. A local privileged user can exploit this vulnerability to gain access to sensitive information.

4) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-5072)

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

The vulnerability exists due to allocation of resources without limits or throttling. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

5) Improper input validation (CVE-ID: CVE-2024-21058)

The vulnerability allows a remote privileged user to manipulate data.

The vulnerability exists due to improper input validation within the Unified Audit in Oracle Database Server. A remote privileged user can exploit this vulnerability to manipulate data.

6) Improper input validation (CVE-ID: CVE-2024-21093)

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

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 gain access to sensitive information.

7) Inadequate encryption strength (CVE-ID: CVE-2023-48795)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.

The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.
