An alert from Cupertino, Calif.-based Symantec described the flaws as "high risk" and warned that a successful exploit could wipe out a user's computer. Attackers could also execute remote code on the targeted system that could potentially render your computer useless.
The vulnerabilities, first discovered by researchers at eEye Digital Security, affect both enterprise and consumer Norton users. Affected products include the Symantec Client Firewall 5.01 and 5.1.1; the Symantec Client Security 1.0, 1.1, 2.0 (SCF 7.1); the Norton Internet Security and Professional 2002, 2003, 2004; Norton Personal Firewall 2002, 2003, 2004; and the Norton AntiSpam 2004.
Independent research firm Secunia rates the flaws as "extremely critical" because they could lead to a destructive worm attack. Secunia CTO Thomas Kristensen says the vulnerabilities could lead to an attack similar to the Slammer worm that exploited Microsoft SQL servers last year.
"It is important that people patch and upgrade their Symantec Firewall Products today as there is no other effective solution against this," Kristensen says.
For Symantec, the discovery of such a serious bug in products designed to provide PC security could be disastrous. The company has used the popularity -- and success -- of the Norton anti-virus brand to gain traction in the enterprise market with VPN and firewall management applications.
To its credit, Symantec wasted no time in confirming the existence of the holes and rushing out fixes. Patches have been released through Symantec LiveUpdate and technical support channels.
According to the company, clients running consumer versions of the affected products who regularly run a manual Symantec LiveUpdate should be automatically protected against this issue. "However, customers should manually run Symantec LiveUpdate to make certain that all available updates have been installed.
