handled RSA padding. An Attacker could possibly use this issue to obtain
sensitive information. (CVE-2025-21587)

It was discovered that the Compiler component of OpenJDK 8 incorrectly
handled compiler transformations. An attacker could possibly use this
issue to cause a denial of service or execute arbitrary code.
(CVE-2025-30691)

It was discovered that the 2D component of OpenJDK 8 did not properly
manage memory under certain circumstances. An attacker could possibly use
this issue to cause a denial of service or execute arbitrary code.
(CVE-2025-30698)

In addition to security fixes, the updated packages contain bug fixes, new
features, and possibly incompatible changes.
