ISC BIND up to 4.9.10 stub Resolver Library getnetbyname memory corruption

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, which was classified as critical, has been found in ISC BIND up to 4.9.10 (Domain Name Software). This issue affects the function getnetbyname of the component stub Resolver Library. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflows in the DNS stub resolver library in ISC BIND 4.9.2 through 4.9.10, and other derived libraries such as BSD libc and GNU glibc, allow remote attackers to execute arbitrary code via DNS server responses that trigger the overflow in the (1) getnetbyname, or (2) getnetbyaddr functions, aka "LIBRESOLV: buffer overrun" and a different vulnerability than CVE-2002-0684.

The weakness was released 02/21/2003 (Website). It is possible to read the advisory at ftp.netbsd.org. The identification of this vulnerability is CVE-2002-0029. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. 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 03/08/2021). Due to its background and reception, this vulnerability has a historic impact.

We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 15033 (Debian DSA-196-1 : bind - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The security flaw can be detected with the following NASL code:

vers = get_kb_item("bind/version");
if(!vers)exit(0);
if (vers =~ "^4\.9\.[2-9]") security_hole(53); 
if (vers =~ "^4\.9\.10") security_hole(53);

Upgrading to version 9.2.2 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at isc.org. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published even before and not after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 12970.

The vulnerability is also documented in the databases at X-Force (10624) and Tenable (15033). Entries connected to this vulnerability are available at 19162 and 19163.
