CVE-2014-2032
Description
Deadwood before 2.3.09, 3.x before 3.2.05, and as used in MaraDNS before 1.4.14 and 2.x before 2.0.09, allow remote attackers to cause a denial of service (out-of-bounds read and crash) by leveraging permission to perform recursive queries against Deadwood, related to missing input validation.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Missing input validation in Deadwood DNS recursive resolver allows remote attackers to cause DoS via out-of-bounds read.
Vulnerability
Deadwood versions before 2.3.09 and 3.x before 3.2.05, as used in MaraDNS before 1.4.14 and 2.x before 2.0.09, contain a missing input validation vulnerability in the processing of recursive queries. This lack of proper bounds checking leads to an out-of-bounds read when handling specially crafted DNS packets [1][2].
Exploitation
An attacker with permission to perform recursive queries against a Deadwood server can send a malicious DNS query. The server fails to validate the query data, resulting in an out-of-bounds read that causes the process to crash. No authentication or special privileges are required beyond network access to the DNS service [2][3].
Impact
Successful exploitation causes a denial of service (DoS) by crashing the Deadwood or MaraDNS process, disrupting DNS resolution. While out-of-bounds reads can potentially leak information, the primary impact is availability [1][2].
Mitigation
The vulnerability is fixed in Deadwood 2.3.09 and 3.2.05, and MaraDNS 1.4.14 and 2.0.09, all released on February 12, 2014. Users are advised to upgrade immediately. No workarounds are documented, and the issue is not listed in the KEV catalog [1][2][3].
