-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Symantec Veritas Storage Foundation
Administrator Service. Authentication is not required to exploit this
vulnerability.

The specific flaw exists within vxsvc.exe process. The problem affecting
the part of the server running on tcp port 2148 is an integer overflow
in the function vxveautil.kv_binary_unpack where a 32-bit field is used
to allocate an amount of memory equal to its value plus 1. This can be
made to miscalculate a heap buffer which can be subsequently overflowed
allowing an attacker to execute arbitrary code under the context of
SYSTEM.
