Detailsinfo

A vulnerability, which was classified as critical, was found in ISC BIND 4.9.8 (Domain Name Software). Affected is the function getnetbyname/getnetbyaddr of the component DNS Resolver. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Buffer overflow in DNS resolver functions that perform lookup of network names and addresses, as used in BIND 4.9.8 and ported to glibc 2.2.5 and earlier, allows remote malicious DNS servers to execute arbitrary code through a subroutine used by functions such as getnetbyname and getnetbyaddr.

The weakness was released 08/12/2002 with Network Associates as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability is traded as CVE-2002-0684. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 11318 (ISC BIND < 9.2.2 DNS Resolver Functions Remote Overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family DNS and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115024 (Red Hat glibc DNS Resolver Buffer Overflow Vulnerabilities).

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (9432), Tenable (11318), SecurityFocus (BID 7228†) and Vulnerability Center (SBV-1540†).
