verifiedexecioctl in verified_exec.c in NetBSD 2.0.2 calls NDINIT with UIO_USERSPACE rather than UID_SYSSPACE, which removes the functionality of the verified exec kernel subsystem and might allow local users to execute Trojan horse programs.

NetBSD 2.0 before 2.0.4, 2.1 before 2.1.1, and 3, when the kernel is compiled with "options DIAGNOSTIC," allows local users to cause a denial of service (kernel assertion panic) via a negative linger time in the SO_LINGER socket option.

kernfs_xread in kernfs_vnops.c in NetBSD before 20050831 does not check for a negative offset when reading the message buffer, which allows local users to read arbitrary kernel memory.

The (1) clcs and (2) emuxki drivers in NetBSD 1.6 through 2.0.2 allow local users to cause a denial of service (kernel crash) by using the set-parameters ioctl on an audio device to change the block size and set the pause state to "unpaused" in the s...

The systrace_exit function in the systrace utility for NetBSD-current and 2.0 before April 16, 2004, and certain FreeBSD ports, does not verify the owner of the /dec/systrace connection before setting euid to 0, which allows local users to gain root ...

Multiple buffer overflows in NetBSD kernel may allow local users to execute arbitrary code and gain privileges.

Multiple syscalls in the compat subsystem for NetBSD before 2.0 allow local users to cause a denial of service (kernel crash) via a large signal number to (1) xxx_sys_kill, (2) xxx_sys_sigaction, and possibly other translation functions.

OpenBSD 3.4 and NetBSD 1.6 and 1.6.1 allow remote attackers to cause a denial of service (crash) by sending an IPv6 packet with a small MTU to a listening port and then issuing a TCP connect to that port.

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that u...

The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails,...
