run into an infinite loop. If an automated system were tricked into
processing excessively large symbols, an attacker could possibly use this
issue to cause a denial of service. (CVE-2024-21138)

properly perform range check elimination. An attacker could possibly use
this issue to cause a denial of service, execute arbitrary code or bypass
Java sandbox restrictions. (CVE-2024-21140)

Sergey Bylokhov discovered that OpenJDK 21 did not properly manage memory
when handling 2D images. An attacker could possibly use this issue to
obtain sensitive information. (CVE-2024-21145)
