A race condition between the select() and accept() calls in NetBSD TCP servers allows remote attackers to cause a denial of service.

umapfs allows local users to gain root privileges by changing their uid through a malicious mount_umap program.

In some cases, NetBSD 1.3.3 mount allows local users to execute programs in some file systems that have the "noexec" flag set.

XFree86 startx command is vulnerable to a symlink attack, allowing local users to create files in restricted directories, possibly allowing them to gain privileges or cause a denial of service.

XFree86 xfs command is vulnerable to a symlink attack, allowing local users to create files in restricted directories, possibly allowing them to gain privileges or cause a denial of service.

Local users can perform a denial of service in NetBSD 1.3.3 and earlier versions by creating an unusual symbolic link with the ln command, triggering a bug in VFS.

The SVR4 /dev/wabi special device file in NetBSD 1.3.3 and earlier allows a local user to read or write arbitrary files on the disk associated with that device.

ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service.

The rwho/rwhod service is running, which exposes machine status and user information.

The BSD profil system call allows a local user to modify the internal data space of a program via profiling and execve.

NetBSD on a multi-homed host allows ARP packets on one network to modify ARP entries on another connected network.

NetBSD allows ARP packets to overwrite static ARP entries.

The asynchronous I/O facility in 4.4 BSD kernel does not check user credentials when setting the recipient of I/O notification, which allows local users to cause a denial of service by using certain ioctl and fcntl calls to cause the signal to be sent to an arbitrary process ID.

rpc.mountd on Linux, Ultrix, and possibly other operating systems, allows remote attackers to determine the existence of a file on the server by attempting to mount that file, which generates different error messages depending on whether the file exists or not.

The at program in IRIX 6.2 and NetBSD 1.3.2 and earlier allows local users to read portions of arbitrary files by submitting the file to at with the -f argument, which generates error messages that at sends to the user via e-mail.

Operating systems with shared memory implementations based on BSD 4.4 code allow a user to conduct a denial of service and bypass memory limits (e.g., as specified with rlimits) using mmap or shmget to allocate memory and cause page faults.

The BSD make program allows local users to modify files via a symlink attack when the -j option is being used.

procfs in BSD systems allows local users to gain root privileges by modifying the /proc/pid/mem interface via a modified file descriptor for stderr.

NetBSD ptrace call on VAX allows local users to gain privileges by modifying the PSL contents in the debugging process.

traceroute in NetBSD 1.3.3 and Linux systems allows local users to flood other systems by providing traceroute with a large waittime (-w) option, which is not parsed properly and sets the time delay for sending packets to zero.
