CWE-20Published: January 9, 2008· Updated: Jun 16, 2026
4.3
CVSS v3.1
Official Description
Sun JRE 5.0 before update 14 allows remote attackers to cause a denial of service (Internet Explorer crash) via an object tag with an encoded applet and an undefined name attribute, which triggers a NULL pointer dereference in jpiexp32.dll when the applet is decoded and passed to the JVM.
Technical Analysis
CVE-2007-0012 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
