high Nessus Plugin ID 192188

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6696-1 advisory.

 Yi Yang discovered that the Hotspot component of OpenJDK 8 incorrectly handled array accesses in the C1 compiler. An attacker could possibly use this issue to cause a denial of service, execute arbitrary code or bypass Java sandbox restrictions. (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.
 (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. (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. (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. (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.
 (CVE-2024-20952)

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.
