Detailsinfo

A vulnerability was found in NetBSD 1.5/1.5.1/1.5.2/1.5.3/1.6 (Operating System) and classified as problematic. This issue affects the function tryelf of the file readelf.c of the component ELF Header Handler. 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. The summary by CVE is:

Buffer overflow in tryelf() in readelf.c of the file command allows attackers to execute arbitrary code as the user running file, possibly via a large entity size value in an ELF header (elfhdr.e_shentsize).

The bug was discovered 03/04/2003. The weakness was released 03/18/2003 as confirmed advisory (CERT.org). The advisory is shared at kb.cert.org. The identification of this vulnerability is CVE-2003-0102. The exploitation is known to be easy. An attack has to be approached locally. 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. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 14 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 14014 (Mandrake Linux Security Advisory : file (MDKSA-2003:030-1)), 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.

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

The vulnerability is also documented in the databases at X-Force (11488), Exploit-DB (22324), Tenable (14014), SecurityFocus (BID 7008†) and OSVDB (6456†). Entry connected to this vulnerability is available at VDB-21082. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
