-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable Symantec VERITAS NetBackup installations. Authentication is
not required to exploit this vulnerability.

The specific flaw exists within the NetBackup Database Manager service
(bpdbm.exe) due to insufficient bounds checking during a call to
sprintf() that copies user-supplied data to a stack-based buffer. The
vulnerable daemon listens on TCP port 13721.

Symantec engineers have addressed these issues in all currently
supported versions of NetBackup. Symantec engineers did additional
reviews and will continue on-going reviews of related file
functionality to further enhance the overall security of Veritas
NetBackup products and to eliminate any additional potential concerns.
