Detailsinfo

A vulnerability was found in NetBSD up to 2.0.2 (Operating System) and classified as problematic. This issue affects an unknown code of the file /tmp of the component imake. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in CVS 1.11.x up to 1.11.15, and 1.12.x up to 1.12.7, when using the pserver mechanism allows remote attackers to execute arbitrary code via Entry lines.

The bug was discovered 05/19/2004. The weakness was shared 11/02/2005 by Stefan Esser (Matt) with NetBSD Team (Website). It is possible to read the advisory at ftp.netbsd.org. The identification of this vulnerability is CVE-2004-0396 since 04/13/2004. The attack needs to be initiated within the local network. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed in ANSI C and been published even before and not after the advisory. The exploit is available at packetstormsecurity.nl. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 14147 (Mandrake Linux Security Advisory : cvs (MDKSA-2004:048)), 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 38273 (CVS Malformed Entry Modified and Unchanged Flag Insertion Heap Overflow Vulnerability).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at netbsd.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. Attack attempts may be identified with Snort ID 13614.
