The IPv6 Neighbor Discovery Protocol (NDP) implementation in HP HP-UX B.11.11, B.11.23, and B.11.31 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity), read private network traffic, and possibly execute arbitrary code via a spoofed message that modifies the Forward Information Base (FIB), a related issue to CVE-2008-2476.

It was discovered that the event logger contains a format string error. An untrusted Java application or applet could possibly use this flaw to cause the Java Virtual Machine to crash, or, potentially, execute arbitrary code with the privileges of the Java Virtual Machine.
