Details
Symantec engineers resolved issues discovered during internal review in which malformed input could potentially cause memory access violations or exhaust system resources. Any of these issues could cause a process crash or DoS and temporary loss of backup capability. In the majority of issues, the affected service would need to be restarted to regain operational capability. In the case of the NetBackup for NetWare Media Server Option products, this can result in the system abending requiring a restart to recover.

Symantec Response
Security updates are available for all supported affected products. Symantec recommends all customers apply the latest updates for their supported product versions to protect against these types of threats.

Symantec knows of no adverse customer impact from this issue.

Best Practices
As part of normal best practices, Symantec recommends:

  • Restrict access to administration or management systems to privileged users.
  • Restrict remote access, if required, to trusted/authorized systems only.
  • Run under the principle of least privilege where possible to limit the impact of exploit by threats such as this.
  • Keep all operating systems and applications updated with the latest vendor patches.
  • Follow a multi-layered approach to security. Run both firewall and antivirus applications, at a minimum, to provide multiple points of detection and protection to both inbound and outbound threats.
  • Deploy network intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in detection of attacks or malicious activity related to exploitation of latent vulnerabilities
