Symantec ManHunt's Protocol Anomaly Detects Sendmail Vulnerability
Customers Are Protected Against This Specific Exploit
CUPERTINO, Calif. - March 5, 2003 - Symantec Corp. (NASDAQ: SYMC), the world leader in Internet security, today announced that Symantec ManHunt's protocol anomaly detection technology detected the Sendmail Header Processing vulnerability, a remotely exploitable vulnerability in Sendmail, one of the most common e-mail servers. Symantec ManHunt customers have been protected against this specific exploit since its discovery without having to update the product.
"Symantec ManHunt's detection ability is one of its key strengths. In addition to classic signature capabilities, ManHunt also provides protocol anomaly detection, which looks for deviations from normal protocol behavior and detects novel attacks," said Frank Huerta, vice president, IDS product delivery at Symantec. "In this case, Symantec ManHunt's protocol anomaly detection detected the Sendmail exploit as a violation of the mail protocol. Our customers were alerted to the attack without having to update the product to protect against this specific vulnerability."
The remotely exploitable vulnerability was discovered in multiple versions of Sendmail. Remote attackers may gain root access (complete control) on affected SMTP servers. As SMTP servers are responsible for delivering and receiving e-mail, sensitive information may also be disclosed or tampered with by attackers. Sendmail is a widely used message transfer agent (MTA) for UNIX and Microsoft Windows systems.
Symantec ManHunt is an advanced network-based intrusion detection system that provides multiple detection methodologies to detect both known and unknown, or "zero day" attacks. ManHunt's core detection capability uses protocol anomaly detection, signature detection with custom signature support, traffic state profiling and statistical flow analysis to identify intrusions and denial of service attacks. ManHunt detects intrusions at speeds of up to 2 gigabits per second, dependent upon system configuration.
