Details
TippingPoint, a division of 3Com, notified Symantec of a format string
overflow vulnerability in VERITAS NetBackup that could potentially allow a
remote attacker to execute arbitrary code. The vulnerability exists in the
authentication service, bpjava-msvc daemon, in the Java user-interface. If
a remote attacker were able to access the service and successfully exploit
this vulnerability, they could potentially execute arbitrary code with the
privileges of the bpjava-msvc daemon, normally root or SYSTEM, on the
targeted system.
Symantec Response
Symantec Engineers have verified this issue and made security updates
available for the supported VERITAS NetBackup products. Symantec strongly
recommends all customers immediately apply the latest updates for their
supported product versions to protect against these types of threats.
The patches listed above for NetBackup DataCenter and NetBackup
BusinessServer 4.5 and for NetBackup Enterprise Server and NetBackup
Server 5.0, 5.1, and 6.0 are available from the following location:
http://support.veritas.com/docs/279085
NOTE: In a recommended installation, VERITAS NetBackup should be
restricted to trusted access only. The VERITAS NetBackup Server or clients
should never be visible external to the network which greatly reduces
opportunities for unauthorized access.
Symantec is unaware of any exploit of or adverse customer impact from this
issue.
Symantec Security Response has released IPS/IDS signatures to detect and
prevent attempts to exploit this issue.
Symantec ManHunt 3.0 signatures are available for update from the Symantec
Security Response Update Center at:
http://securityresponse.symantec.com/avcenter/security/Content/Product/Prod
uct_MH.html
Symantec Network Security Appliance 7100 signatures are available for
update from the Symantec Security Response Update Center at:
http://securityresponse.symantec.com/avcenter/security/Content/Product/Prod
uct_SNS.html
Symantec Gateway Security 3.0 signatures are available for update from the
Symantec Security Response Update Center at:
http://securityresponse.symantec.com/avcenter/security/Content/Product/Prod
uct_SGS.html
Symantec Client Security 2.0 and 3.0 signatures are available for update
via LiveUpdate and from the Security Response Update Center at:
http://www.symantec.com/avcenter/security/Content/Product/Product_SCS.html
Customers using Symantec Client Security 2.0 and 3.0 should have already
uploaded this signature if they run LiveUpdate regularly. If not, Symantec
recommends customers manually run Symantec LiveUpdate to ensure they have
the most current protection.
As part of normal best practices, Symantec strongly recommends:
=B7 Restricting access to administration or management systems to privileged
users.
=B7 Restricting remote access, if required, to trusted/authorized systems
only.
=B7 Running under the principle of least privilege where possible to limit
the impact of exploit by threats such as this.
=B7 Keeping all operating systems and applications updated with the latest
vendor patches.
=B7 Following 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.
=B7 Deploying 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
