performing bounds when handling certain UTF-8 strings, which could lead to
a buffer overflow. An attacker could possibly use this issue to cause a
denial of service or execute arbitrary code. (CVE-2024-21131)

It was discovered that the Hotspot component of OpenJDK 8 could be made to
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)

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)

Yakov Shafranovich discovered that the Concurrency component of OpenJDK 8
incorrectly performed header validation in the Pack200 archive format. An
attacker could possibly use this issue to cause a denial of service.
