Detailsinfo

A vulnerability, which was classified as critical, has been found in ISC BIND up to 8.2.x (Domain Name Software). Affected by this issue is an unknown part 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. CVE summarizes:

The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, use the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary ("read buffer overflow"), allowing remote attackers to cause a denial of service (crash).

The bug was discovered 10/01/2002. The weakness was shared 10/11/2002 by LINUX as confirmed advisory (CERT.org). The advisory is shared for download at kb.cert.org. This vulnerability is handled as CVE-2002-1146. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 10 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 14109 (Mandrake Linux Security Advisory : glibc (MDKSA-2004:009)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 15047 (Buffer Overflow Vulnerabilities in Multiple DNS Resolver Libraries).

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 years after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (10295), Tenable (14109), SecurityFocus (BID 6116†), OSVDB (14877†) and Vulnerability Center (SBV-7696†). VulDB is the best source for vulnerability data and more expert information about this specific topic.
