Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2024-21211)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

The vulnerability exists due to improper input validation within the Compiler component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.


2) Improper input validation (CVE-ID: CVE-2025-21553)

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

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 read and manipulate data.


3) 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.


4) Untrusted search path (CVE-ID: CVE-2022-26345)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to uncontrolled search path element, which leads to security restrictions bypass and privilege escalation.


5) Resource exhaustion (CVE-ID: CVE-2023-52428)

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

The vulnerability exists due to improper validation of user requests by the PasswordBasedDecrypter (PBKDF2) component. A remote attacker can send a specially crafted request using a large JWE p2c header, trigger resource exhaustion and perform a denial of service (DoS) attack.
