CVE-2008-5353: Sun JDK: Insecure deserialization

CVE-2008-5353 has a CVSS v2 base score of 10.0 (the maximum on that scale) and affects Sun JDK. Per its scoring, it can be exploited over the network, without authentication. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

The Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier does not properly enforce context of ZoneInfo objects during deserialization, which allows remote attackers to run untrusted applets and applications in a privileged context, as demonstrated by "deserializing Calendar objects".
