Symantec Norton Internet Security up to 5.01 SYMDNS.SYS stack-based overflow

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability has been found in Symantec Norton Internet Security up to 5.01 and classified as very critical. Affected by this vulnerability is some unknown functionality in the library SYMDNS.SYS. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Multiple vulnerabilities in SYMDNS.SYS for Symantec Norton Internet Security and Professional 2002 through 2004, Norton Personal Firewall 2002 through 2004, Norton AntiSpam 2004, Client Firewall 5.01 and 5.1.1, and Client Security 1.0 through 2.0 allow remote attackers to cause a denial of service or execute arbitrary code via (1) a manipulated length byte in the first-level decoding routine for NetBIOS Name Service (NBNS) that modifies an index variable and leads to a stack-based buffer overflow, (2) a heap-based corruption problem in an NBNS response that is missing certain RR fields, and (3) a stack-based buffer overflow in the DNS component via a Resource Record (RR) with a long canonical name (CNAME) field composed of many smaller components.

The bug was discovered 04/19/2004. The weakness was shared 05/12/2004 by Derek Soeder (DiGiT) with eEye Digital Security as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is known as CVE-2004-0444 since 05/04/2004. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 11/19/2024).

The vulnerability was handled as a non-public zero-day exploit for at least 23 days. During that time the estimated underground price was around $25k-$100k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 34025 (Symantec Client Firewall SYMDNS.SYS Multiple Vulnerabilities).

Proper firewalling of is able to address this issue. A possible mitigation has been published immediately after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 2563. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 2808.

The vulnerability is also documented in the databases at X-Force (16141), SecurityFocus (BID 10335†), OSVDB (6099†), Secunia (SA11066†) and SecurityTracker (ID 1010144†). The entry VDB-21920 is related to this item. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
