CVE-2017-1000378
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 m...
CVE-2017-1000375
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.
CVE-2017-1000374
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.
CVE-2015-8212
CGI handling flaw in bozohttpd in NetBSD 6.0 through 6.0.6, 6.1 through 6.1.5, and 7.0 allows remote attackers to execute arbitrary code via crafted arguments, which are handled by a non-CGI aware program.

The glob implementation in tnftpd (formerly lukemftpd), as used in Apple OS X before 10.11, allows remote attackers to cause a denial of service (memory consumption and daemon outage) via a STAT command containing a crafted pattern, as demonstrated b...
CVE-2014-7250
The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets...

The fetch_url function in usr.bin/ftp/fetch.c in tnftp, as used in NetBSD 5.1 through 5.1.4, 5.2 through 5.2.2, 6.0 through 6.0.6, and 6.1 through 6.1.5 allows remote attackers to execute arbitrary commands via a | (pipe) character at the end of an H...
CVE-2014-3566
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.
