Summaryinfo

A vulnerability, which was classified as problematic, has been found in NetBSD up to 4.0. This issue affects the function clnp_route. The manipulation of the argument structure leads to memory corruption. This vulnerability is uniquely identified as CVE-2007-1677. No exploit exists.

Detailsinfo

A vulnerability was found in NetBSD up to 4.0 (Operating System) and classified as critical. This issue affects the function clnp_route. The manipulation of the argument structure 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:

Multiple buffer overflows in the ISO network protocol support in the NetBSD kernel 2.0 through 4.0_BETA2, and NetBSD-current before 20070329, allow local users to execute arbitrary code via long parameters to certain functions, as demonstrated by a long sockaddr structure argument to the clnp_route function.

The weakness was disclosed 03/29/2007 by Christer Oberg (Website). The advisory is shared at ftp.netbsd.org. The identification of this vulnerability is CVE-2007-1677 since 03/26/2007. An attack has to be approached locally. The successful exploitation needs a simple authentication. Technical details are known, but no exploit is available.

It is declared as proof-of-concept.

The vulnerability is also documented in the databases at X-Force (33381), SecurityFocus (BID 23193†), OSVDB (43596†) and SecurityTracker (ID 1017832†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
