Overview
Symantec resolved a DNS cache poisoning vulnerability that was reported to
impact the Symantec Gateway Security products noted below. Under specific
conditions and configurations, incorrect or false DNS records could be
inserted into the DNS cache tables. It would then be possible that legitimate
DNS requests would return incorrect responses.
Affected Components
Symantec Gateway Security 5400 Series, v2.0
Symantec Gateway Security 5300 Series, v1.0
Symantec Enterprise Firewall, v7.0.x (Windows and Solaris)
Symantec Enterprise Firewall v8.0 (Windows and Solaris)
Symantec VelociRaptor, Model 1100/1200/1300
Symantec VelociRaptor, Model 500/700/1000
Details
Symantec Security Gateway products include a DNS proxy, DNSd, which can be
configured to function as a DNS server. Under specific conditions, DNSd may
be susceptible to DNS cache poisoning. DNS cache poisoning occurs when
incorrect or false DNS records are inserted into a DNS server's cache tables.
The results of inadvertent or intentional DNS cache poisoning can be
unintentional loss of service or potentially malicious activity.
Symantec Response
Symantec released a hotfix to address this issue that provides additional
authentication and validation checks for each response directed to DNSd.
Symantec recommends customers apply the appropriate hotfix for their affected
product versions immediately to protect against this type of threat. Product
specific hotfixes are available via the Symantec Enterprise Support site
http://www.symantec.com/techsupp.
Symantec is not aware of any active attempts against or customer impact from
this issue.
