The kernel in NetBSD-current before September 28, 2005 allows local users to cause a denial of service (system crash) by using the SIOCGIFALIAS ioctl to gather information on a non-existent alias of a network interface, which causes a NULL pointer dereference.

NetBSD 1.6, 2.0, 2.1 and 3.0 allows local users to cause a denial of service (memory exhaustion) by using the sysctl system call to lock a large buffer into physical memory.

Intel RNG Driver in NetBSD 1.6 through 3.0 may incorrectly detect the presence of the pchb interface, which will cause it to always generate the same random number, which allows remote attackers to more easily crack encryption keys generated from the interface.

The audio_write function in NetBSD 3.0 allows local users to cause a denial of service (kernel crash) by using the audiosetinfo ioctl to change the sample rate of an audio device.

The ip6_savecontrol function in NetBSD 2.0 through 3.0, under certain configurations, does not check to see if IPv4-mapped sockets are being used before processing IPv6 socket options, which allows local users to cause a denial of service (crash) by creating an IPv4-mapped IPv6 socket with the SO_TIMESTAMP socket option set, then sending an IPv4 packet through the socket.

Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service (panic), obtain sensitive information, and possibly execute arbitrary code via crafted Link Control Protocol (LCP) packets with an option length that exceeds the overall length, which triggers the overflow in (1) pppoe and (2) ippp. NOTE: this issue was originally incorrectly reported for the ppp driver.

Integer overflow in the FreeBSD compatibility code (freebsd_misc.c) in NetBSD-current, NetBSD-3, NetBSD-2.0, and NetBSD-2 before 20050913; and NetBSD-1.6 before 20050914; allows local users to cause a denial of service (heap corruption or system crash) and possibly gain root privileges.

Denial of Service vulnerability in BIND 8 Releases via maliciously formatted DNS messages.

Denial of Service vulnerabilities in BIND 4.9 and BIND 8 Releases via CNAME record and zone transfer.

Teardrop IP denial of service.

Land IP denial of service.

FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce.

Buffer overflow of rlogin program using TERM environmental variable.

Listening TCP ports are sequentially allocated, allowing spoofing attacks.

Buffer overflow in rwhod on AIX and other operating systems allows remote attackers to execute arbitrary code via a UDP packet with a long hostname.

Buffer overflow in Vixie Cron library up to version 3.0 allows local users to obtain root access via a long environmental variable.

Buffer overflow in BNU UUCP daemon (uucpd) through long hostnames.

mmap function in BSD allows local attackers in the kmem group to modify memory through devices.

FreeBSD mmap function allows users to modify append-only or immutable files.

NetBSD netstat command allows local users to access kernel memory.
