Technical ContextAI · show details
This vulnerability is classified as Access of Resource Using Incompatible Type (Type Confusion) (CWE-843), which allows attackers to execute arbitrary code by exploiting type confusion in the application. Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 2 and earlier, 6 Update 30 and earlier, and 5.0 Update 33 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Concurrency. NOTE: the previous information was obtained from the February 2012 Oracle CPU. Oracle has not commented on claims from a downstream vendor and third party researchers that this issue occurs because the AtomicReferenceArray class implementation does not ensure that the array is of the Object[] type, which allows attackers to cause a denial of service (JVM crash) or bypass Java sandbox restrictions. NOTE: this issue was originally mapped to CVE-2011-3571, but that identifier was already assigned to a different issue. Affected products include: Sun Jre, Oracle Jre, Debian Debian Linux, Suse Linux Enterprise Desktop, Suse Linux Enterprise Java.

SSVC AssessmentENISA
Priority Score
Attack Technique
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
