Official Description
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.
Technical Analysis
CVE-2007-1677 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
