Symantec Backup Exec for Windows Server bengine.exe denial of service
| backupexec-bengine-dos (38677) |  Low Risk |
Description:
Symantec Backup Exec for Windows Server is vulnerable to a denial of service, caused by multiple integer overflow errors in the Backup Exec Job Engine service (bengine.exe). By sending a specially-crafted packet to TCP port 5633, a remote attacker could cause the service to enter into an infinite loop and consume an overly large amount of CPU resources and all available memory, resulting in a denial of service.
Platforms Affected:
- Microsoft, Windows 2003 Server
- Symantec, BackupExec System Recovery 11d build 11.0.6.6235
- Symantec, BackupExec System Recovery 11d build 11.0.7170

Consequences:
Denial of Service
