Description:
Some vulnerabilities have been reported in Symantec Veritas Netbackup, which can be exploited by malicious people to compromise a vulnerable system.

1) A logic error in the main Netbackup service (bpcd.exe) can be exploited via command chaining to make the service execute arbitrary commands.

2) A boundary error in the main Netbackup service (bpcd.exe) when parsing long requests can be exploited to cause a stack-based buffer overflow by passing an overly long request with a malformed length field to the service.

3) A boundary error in the main Netbackup service (bpcd.exe) when parsing CONNECT_OPTIONS requests can be exploited to cause a stack-based buffer overflow via an overly long request.

Solution:
Apply patches.
