Releases

• Ubuntu 24.04 LTS
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• openjdk-17 - Open Source Java implementation

Details

It was discovered that the Hotspot component of OpenJDK 17 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. (CVE-2024-21131)

It was discovered that the Hotspot component of OpenJDK 17 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 17 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)

Sergey Bylokhov discovered that OpenJDK 17 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 17 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)
