CVSS v3.1

Official Description

Multiple buffer overflows in Sun Java Web Start in JDK and JRE 6 before Update 4, JDK and JRE 5.0 before Update 16, and SDK and JRE 1.4.x before 1.4.2_18 allow context-dependent attackers to gain privileges via an untrusted application, as demonstrated by (a) an application that grants itself privileges to (1) read local files, (2) write to local files, or (3) execute local programs; and as demonstrated by (b) a long value associated with a java-vm-args attribute in a j2se tag in a JNLP file, which triggers a stack-based buffer overflow in the GetVMArgsOption function; aka CR 6557220.

Technical Analysis

CVE-2008-3111 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.
