Backup Exec: multiple Denial of Service (DoS) issues
addressed in Application Memory
Revision History
None
Severity
Medium
Overview
During internal reviews of
supported Backup Exec products and versions, Symantec identified and fixed
multiple memory errors in which a specifically malformed packet could result in
a process crash or a denial of service (DoS) preventing ongoing backup
capability until the Backup Exec Remote Agent (for Windows, for NetWare, or
RALUS) service is restarted.
Affected Products
The Backup Exec for NetWare
Servers media servers and Remote Agents for NetWare, Windows, and Linux/Unix are
affected. Each of these components in a Backup Exec for NetWare Servers
installation need to be updated.
Backup Exec 9.2 for NetWare
Servers - All Agents (Netware, Windows, & Linux/Unix)
Backup Exec 9.1 for NetWare
Servers - All Agents (NetWare, Windows, & Linux/Unix)
Note: Backup Exec 9.0 for NetWare Servers is EOL

prior to version 9.0 are not affected.
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 Backup Exec RAWS
service would need to be stopped and restarted to regain operational
capability.

Best Practices
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 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
