Detailsinfo

A vulnerability was found in OpenBSD 3.9/4.0 (Operating System). It has been classified as very critical. Affected is an unknown functionality of the file kern/uipc_mbuf2.c of the component ICMPv6 Packet Handler. The manipulation of the argument mbuf with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Buffer overflow in kern/uipc_mbuf2.c in OpenBSD 3.9 and 4.0 allows remote attackers to execute arbitrary code via fragmented IPv6 packets due to "incorrect mbuf handling for ICMP6 packets." NOTE: this was originally reported as a denial of service.
