Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2020-36843)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the EdDSA implementation in affected plugin exhibits signature malleability. A remote user can create new valid signatures different from previous signatures for a known message.
2) Covert Timing Channel (CVE-ID: CVE-2024-13176)
The vulnerability allows a remote attacker to recover a private key.
The vulnerability exists due to a timing side-channel in ECDSA signature computations. A remote attacker can recover the private key and decrypt data.
Successful exploitation of the vulnerability requires that the attacker's process must either be located in the same physical computer or must have a very fast network connection with low latency.
3) Improper input validation (CVE-ID: CVE-2025-30702)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Fleet Patching & Provisioning in Oracle Database Server. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
4) Improper input validation (CVE-ID: CVE-2025-30694)
The vulnerability allows a remote authenticated user to read and manipulate data.
The vulnerability exists due to improper input validation within the XML Database in Oracle Database Server. A remote authenticated user can exploit this vulnerability to read and manipulate data.
5) Improper input validation (CVE-ID: CVE-2025-30733)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the RDBMS Listener in Oracle Database Server. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
6) Improper input validation (CVE-ID: CVE-2025-30701)
The vulnerability allows a remote authenticated user to read and manipulate data.
The vulnerability exists due to improper input validation within the RAS Security in Oracle Database Server. A remote authenticated user can exploit this vulnerability to read and manipulate data.
7) Improper input validation (CVE-ID: CVE-2025-30736)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Java VM in Oracle Database Server. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
