==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in OpenJDK 8.

Software Description:
- openjdk-8: Open Source Java implementation

Details:

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

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

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.
(CVE-2024-21144)

Sergey Bylokhov discovered that OpenJDK 8 did not properly manage memory
when handling 2D images. An attacker could possibly use this issue to
obtain sensitive information. (CVE-2024-21145)

It was discovered that the Hotspot component of OpenJDK 8 incorrectly
handled memory when performing range check elimination under certain
circumstances. An attacker could possibly use this issue to cause a
denial of service, execute arbitrary code or bypass Java sandbox
restrictions. (CVE-2024-21147)
