Detailsinfo

A vulnerability has been found in ntp up to 4.2.x (Network Management Software) and classified as critical. Affected by this vulnerability is the function crypto_recv of the file ntp_crypto.c. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in the crypto_recv function in ntp_crypto.c in ntpd in NTP before 4.2.4p7 and 4.2.5 before 4.2.5p74, when OpenSSL and autokey are enabled, allows remote attackers to execute arbitrary code via a crafted packet containing an extension field.

The weakness was published 05/19/2009 as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is known as CVE-2009-1252 since 04/07/2009. 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.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 38844 (Mandriva Linux Security Advisory : ntp (MDVSA-2009:117)), 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 116532 (HP-UX Running XNTP Remote Execution of Arbitrary Code Vulnerability (HPSBUX02437)).

Upgrading to version 4.2.5p56 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 8717.

The vulnerability is also documented in the databases at X-Force (50617), Tenable (38844), SecurityFocus (BID 35017†), Secunia (SA35137†) and SecurityTracker (ID 1022243†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
