Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2025-47219)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the MOV/MP4 demuxer. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
2) Improper input validation (CVE-ID: CVE-2026-21947)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the JavaFX component in Oracle Java SE. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
3) Integer overflow (CVE-ID: CVE-2025-6052)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in GString when handling long string. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and perform a denial of service (DoS) attack.
4) Improper input validation (CVE-ID: CVE-2026-21925)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the RMI component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
5) Integer overflow (CVE-ID: CVE-2025-6021)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the xmlBuildQName() function in tree.c . A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Improper input validation (CVE-ID: CVE-2026-21933)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Networking component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
7) Improper input validation (CVE-ID: CVE-2026-21932)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the AWT, JavaFX component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
8) Improper input validation (CVE-ID: CVE-2026-21945)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the Security component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.
9) Use-after-free (CVE-ID: CVE-2025-7425)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the xsltSetSourceNodeFlags() function. A remote attacker can pass specially crafted XML input to the application, trigger memory corruption and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
10) Use after free (CVE-ID: CVE-2025-43368)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in WebKit Process Model. A remote attacker can trick the victim into opening a specially crafted website and crash the browser.
