Summary
Kwetsbaarheden verholpen in Oracle Java SE
Notes
The Netherlands Cyber Security Center (henceforth: NCSC-NL) maintains this page to enhance access to its information and security advisories. The use of this security advisory is subject to the following terms and conditions: NCSC-NL makes every reasonable effort to ensure that the content of this page is kept up to date, and that it is accurate and complete. Nevertheless, NCSC-NL cannot entirely rule out the possibility of errors, and therefore cannot give any warranty in respect of its completeness, accuracy or continuous keeping up-to-date. The information contained in this security advisory is intended solely for the purpose of providing general information to professional users. No rights can be derived from the information provided therein. NCSC-NL and the Kingdom of the Netherlands assume no legal liability or responsibility for any damage resulting from either the use or inability of use of this security advisory. This includes damage resulting from the inaccuracy of incompleteness of the information contained in the advisory. This security advisory is subject to Dutch law. All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.
Feiten: Oracle heeft 3 kwetsbaarheden verholpen in Oracle Java SE, waaronder Oracle GraalVM for JDK en Oracle GraalVM Enterprise Edition.
Interpretaties: De kwetsbaarheden betreffen verschillende beveiligingsproblemen in Oracle Java SE-producten, waarbij niet-geauthenticeerde kwaadwillenden via netwerktoegang kwetsbaarheden in de Compiler-component kunnen misbruiken. De kwetsbaarheden hebben CVSS-scores in de categorie hoog. Alle drie de kwetsbaarheden kunnen volgens Oracle zonder authenticatie op afstand worden misbruikt. Succesvol misbruik kan onder meer leiden tot het verkrijgen van ongeautoriseerde toegang tot gevoelige informatie, het wijzigen van gegevens en het verstoren van de beschikbaarheid van getroffen systemen. Geen van de kwetsbaarheden is als kritiek aangemerkt. CVE-2026-83357 en CVE-2026-83408 hebben met een CVSS-score van 8,1 de hoogste score en bevinden zich in de Compiler-component van Oracle GraalVM for JDK. Voor beide kwetsbaarheden is geen authenticatie of gebruikersinteractie vereist. Oracle geeft aan dat de kwetsbaarheden moeilijk te misbruiken zijn, maar dat succesvolle exploitatie kan leiden tot volledige overname van het getroffen product.
Oplossingen: Oracle heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
