Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2025-21587)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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

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


2) Improper input validation (CVE-ID: CVE-2025-30698)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


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

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:H/VA:H/SC:H/SI:N/SA:N/E:U/U:Green


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.


4) Out-of-bounds write (CVE-ID: CVE-2025-27363)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can pass a specially crafted font to the application that is using an affected version of the library, trigger an out-of-bounds write and execute arbitrary code on the target system.
