The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6929-1 advisory.
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)
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
