Symantec Storage Foundation Solutions Suites: Veritas Volume Replicator,
Denial of Service in Veritas Administrative Service
Remote Access Network access or authorized user interaction required
Local Access No
Authentication Required No
Exploit publicly available No
A Denial of Service (DoS) vulnerability has been identified and resolved in
the Symantec Veritas Volume Replicator (VVR) option, specifically in the
administrative service. Symantec's VVR ships as a licensable option with
Symantec's Storage Foundation Solutions Suites. If the VVR option is installed,
successful implementation of a DoS attack could terminate the service. In
some circumstances, resource exhaustion as a result of the DoS could
potentially lead to additional system degradation.

iDefense notified Symantec of a DoS vulnerability identified in the Symantec
VVR administrative service. The DoS was caused by failure to properly validate
incoming data passed to the VVR service. A specifically crafted packet passed
to the vulnerable service could result in the VVR administrative service
terminating unexpectedly. The VVR administration service will require a
restart. This type of attack could also potentially lead to degraded application
functions on the targeted system or to the overall system due to excessive
CPU resource consumption during memory allocation attempts prior to VVR
administrative service termination.
This DoS, if successfully exploited, would more likely be the result of an
internal attack by an authorized malicious user on the network since network
access would normally be required to reach the affected service port. Any
potentially successful attack by a non-authorized remote attacker would most
likely be a scenario of interactive user involvement by enticing a user to
run or allow malicious code to be run that could successfully impact a
Symantec takes the security of our products and our customers very seriously.
Symantec engineers have verified and corrected these issues in all currently
supported vulnerable versions of Symantec's Veritas Volume Replicator.
Updates are available for all supported products. Symantec recommends customers
apply the latest product update available for their supported product versions
to enhance their security posture and protect against potential security
threats of this nature.
To determine if the VVR option is installed on a system
Symantec Veritas Storage Foundation Suite for Windows:
1. from a command prompt, run the command "vxrvg.exe", as system or domain
2. if the command is NOT found, the VVR option is not installed and the
system is not vulnerable
3. if the command IS found, the system is vulnerable and the appropriate
solution should be applied
Symantec Veritas Storage Foundation Suite for *nix platforms
1. run the command: /sbin/vxlictest -n "VERITAS Volume Manager" -f "VVR"
2. if the license is NOT found, the VVR option is not installed and the
system is not vulnerable
3. if the license IS found, the system is vulnerable and the appropriate
solution should be applied
Note: Should a customer determine at a later date to install the VVR option,
the appropriate updates must be applied.
Symantec knows of no exploitation of or adverse customer impact from this issue.
The location for patches listed above for affected products can be found in
the following: http://support.veritas.com/docs/286807
As part of normal best practices, Symantec strongly 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.
* Keep all operating systems and applications updated with the latest
* 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
The Common Vulnerabilities and Exposures (CVE) initiative has assigned CVE
Candidate CVE-2007-1593 to this issue.
This issue is a candidate for inclusion in the CVE list (http://cve.mitre.org),
which standardizes names for security problems.
Symantec would like to thank iDefense for reporting these issues and for
providing full coordination while Symantec resolved them.
