Details:

Andy Boothe discovered that the Networking component of OpenJDK 8 did not
properly handle access under certain circumstances. An unauthenticated
attacker could possibly use this issue to cause a denial of service.
(CVE-2024-21208)

It was discovered that the Hotspot component of OpenJDK 8 did not properly
handle vectorization under certain circumstances. An unauthenticated
attacker could possibly use this issue to access unauthorized resources
and expose sensitive information. (CVE-2024-21210, CVE-2024-21235)

properly handle deserialization under certain circumstances. An
unauthenticated attacker could possibly use this issue to cause a denial
of service. (CVE-2024-21217)

It was discovered that the Hotspot component of OpenJDK 8 was not properly
bounding 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. This issue was only addressed in Ubuntu 16.04 LTS.
(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. This issue was only addressed in Ubuntu
16.04 LTS. (CVE-2024-21138)

It was discovered that the Hotspot component of OpenJDK 8 did not properly

bypass Java sandbox restrictions. This issue was only addressed in Ubuntu
16.04 LTS. (CVE-2024-20918)

It was discovered that the Hotspot component of OpenJDK 8 did not
properly verify bytecode in certain situations. An attacker could
possibly use this issue to bypass Java sandbox restrictions. This
issue was only addressed in Ubuntu 16.04 LTS. (CVE-2024-20919)

It was discovered that the Hotspot component of OpenJDK 8 had an
optimization flaw when generating range check loop predicates. An attacker
could possibly use this issue to cause a denial of service, execute
arbitrary code or bypass Java sandbox restrictions. This issue was only
addressed in Ubuntu 16.04 LTS. (CVE-2024-20921)

Valentin Eudeline discovered that OpenJDK 8 incorrectly handled certain
options in the Nashorn JavaScript subcomponent. An attacker could
possibly use this issue to execute arbitrary code. This issue was only
addressed in Ubuntu 16.04 LTS. (CVE-2024-20926)

It was discovered that OpenJDK 8 could produce debug logs that contained
private keys used for digital signatures. An attacker could possibly use
this issue to obtain sensitive information. This issue was only addressed
in Ubuntu 16.04 LTS. (CVE-2024-20945)

Hubert Kario discovered that the TLS implementation in OpenJDK 8 had a
timing side-channel and incorrectly handled RSA padding. A remote attacker
could possibly use this issue to recover sensitive information. This
issue was only addressed in Ubuntu 16.04 LTS. (CVE-2024-20952)
