Omschrijving

IBM heeft kwetsbaarheden verholpen in AIX en PowerVM VIOS. Ook heeft IBM eerdere kwetsbaarheden in, onder andere, DB2, WebSphere, Oracle producten als Java en GraalVM, PostgreSQL, OpenSSH en Perl verholpen voor de producten geproduceerd voor AIX.

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot de volgende categorieën schade:

  • Denial-of-Service
  • Omzeilen van een beveiligingsmaatregel
  • Uitvoer van willekeurige code (root/admin-rechten)
  • Uitvoer van willekeurige code (gebruikersrechten)
  • Toegang tot gevoelige gegevens
  • Manipulatie van gegevens
  • Verhogen van privileges

Oplossingen

De leveranciers hebben updates uitgebracht voor PostgreSQL, IBM AIX, IBM PowerVM VIOS, Perl modules, OpenSSH, Oracle Java SE, Oracle GraalVM, OpenJDK, IBM Db2 Client en Server, en Oracle Communications Cloud Native Core Certificate Management om de beschreven kwetsbaarheden te verhelpen.
