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

The vulnerability exists due to improper input validation within the 2D component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.


3) Heap-based buffer overflow (CVE-ID: CVE-2025-2900)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a defect in its native AES/CBC encryption implementation. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Stack-based buffer overflow (CVE-ID: CVE-2025-4447)

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability occurs when modifying a file on disk that is read when the JVM starts. A local user can trigger stack-based buffer overflow and execute arbitrary code on the target system.
