Apache Portable Runtime (APR) is vulnerable to a denial of service, caused by an error in the aprfnmatch() function when processing specific patterns with the "" wildcard. A remote attacker could exploit this vulnerability to consume all available CPU and memory resources resulting in a denial of service.

Multiple stack consumption vulnerabilities in the kernel in NetBSD 4.0, 5.0 before 5.0.3, and 5.1 before 5.1.1, when IPsec is enabled, allow remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a crafted (1) IPv4 or (2) IPv6 packet with nested IPComp headers.

Multiple libc/glob(3) flaws were reported [1] that affect various BSD libc implementations. In particular, globs containing braces could lead to resource exhaustion.

One such vulnerable application is Pure-FTPd. This has been corrected in upstream version 1.0.32, where support for braces expansion in directory listings was disabled.

The fetchurl 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 HTTP redirect.

bozotic HTTP server (aka bozohttpd) before 20140708, as used in NetBSD, truncates paths when checking .htpasswd restrictions, which allows remote attackers to bypass the HTTP authentication scheme and access restrictions via a long path.
