  • Only the versions listed above are affected
  • Symantec FileStore (SFS) is not affected in the default configuration

Details

Tipping Point ZDI notified Symantec of buffer overflow vulnerabilities in the Veritas Enterprise Administrator service (vxsvc) shared component shipped with multiple Symantec products. These overflows are caused by failure to properly validate incoming data. If successful, an attacker could potentially leverage these issues to execute arbitrary code with administrative privileges on the targeted system.

 

Symantec Response

Symantec engineers have verified these vulnerabilities exist in the versions listed in the above table. These vulnerabilities have been addressed in all supported versions. Symantec engineers did additional reviews, and will continue on-going review of related functionality to further enhance overall security of the Veritas Enterprise Administrator service (vxsvc) and to eliminate any additional potential concerns. The affected port should not be available external to the network in the default configuration, so would require access to the network environment to attempt to exploit.

 

Symantec recommends all customers update affected products (refer the above table for update details) as soon as possible to protect against potential attempts to exploit these issues.

 

Symantec is not aware of any exploitation of, or adverse customer impact from these issues.

Mitigation/Workaround

Refer TECH165536 for workaround details.

 

Best Practices

As part of normal best practices, Symantec strongly recommends:

  • Restrict access to administration or management systems to privileged users.
  • Disable remote access or restrict it to trusted/authorized systems only.
  • Keep all operating systems and applications updated with the latest vendor patches.
  • Follow a multi-layered approach to security. Run both firewall and anti-malware applications, at a minimum, to provide multiple points of detection and protection to both inbound and outbound threats.
  • Deploy network and host-based 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
