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 kwetsbaarheden verholpen in Oracle Java SE, Oracle GraalVM for JDK en Oracle GraalVM Enterprise Edition.
Interpretaties: De kwetsbaarheden betreffen meerdere ondersteunde versies van Oracle Java SE, Oracle GraalVM for JDK en Oracle GraalVM Enterprise Edition. Een onbevoegde aanvaller met netwerktoegang kan via verschillende aanvalsvectoren ongeautoriseerde toegang verkrijgen tot bepaalde of alle beschikbare data, waarbij sommige kwetsbaarheden leiden tot volledige compromittering van het systeem inclusief privilege-escalatie en uitvoering van ongeautoriseerde acties. Daarnaast zijn er kwetsbaarheden die een denial of service veroorzaken door het laten crashen of vastlopen van systemen, onder andere via sandboxed Java Web Start-applicaties en applets. Sommige kwetsbaarheden zijn te misbruiken via HTTP of TLS zonder authenticatie. De impact varieert van ongeautoriseerde gegevensonthulling tot verstoring van de beschikbaarheid van de Java runtime-omgevingen.
Oplossingen: Oracle heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
