CVE-2011-0547

Múltiples desbordamientos de enteros en vxsvc.exe en el servicio VERITAS Enterprise Administrator en Symantec Veritas Storage Foundation v5.1 y anteriores, Veritas Storage Foundation Cluster File System (SFCFS) v5.1 y anteriores, Veritas Storage Foundation Cluster File Enterprise System de Oracle RAC (SFCFSORAC) v5.1 y anteriores, Veritas Dynamic Multi-Pathing (DMP) v5.1 y NetBackup PureDisk v6.5.x a v6.6.1.x permite a atacantes remotos ejecutar código de su elección a través de (1) una cadena Unicode modificada relacionada con la función vxveautil.value_binary_unpack, (2) una cadena ASCII debidamente modificada relacionada con la función vxveautil.value_binary_unpack, o (3) un valor determinado en la función vxveautil.kv_binary_unpack, que da lugar a un desbordamiento de búfer.

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.
