A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.

The IPv6 implementation in FreeBSD and NetBSD (unknown versions, year 2012 and earlier) allows remote attackers to cause a denial of service via a flood of ICMPv6 Neighbor Solicitation messages, a different vulnerability than CVE-2011-2393.

A flaw exists in NetBSD's implementation of the stack guard page that allows attackers to bypass it resulting in arbitrary code execution using certain setuid binaries. This affects NetBSD 7.1 and possibly earlier versions.

NetBSD maps the run-time link-editor ld.so directly below the stack region, even if ASLR is enabled, this allows attackers to more easily manipulate memory leading to arbitrary code execution. This affects NetBSD 7.1 and possibly earlier versions.

The NetBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects NetBSD 7.1 and possibly earlier versions.
