traceroute in NetBSD 1.3.3 and Linux systems allows local unprivileged users to modify the source address of the packets, which could be used in spoofing attacks.

NetBSD 1.4.2 and earlier allows remote attackers to cause a denial of service by sending a packet with an unaligned IP timestamp option.

NetBSD 1.4.2 and earlier allows local users to cause a denial of service by repeatedly running certain system calls in the kernel which do not yield the CPU, aka "cpu-hog".

The undocumented semconfig system call in BSD freezes the state of semaphores, which allows local users to cause a denial of service of the semaphore system by using the semconfig call.

ftpd in NetBSD 1.4.2 does not properly parse entries in /etc/ftpchroot and does not chroot the specified users, which allows those users to access other files outside of their home directory.

FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers.

security flaw

Buffer overflow in mopd (Maintenance Operations Protocol loader daemon) allows remote attackers to execute arbitrary commands via a long file name.

security flaw

mopd (Maintenance Operations Protocol loader daemon) does not properly cleanse user-injected format strings, which allows remote attackers to execute arbitrary commands.

Format string vulnerability in pw_error function in BSD libutil library allows local users to gain root privileges via a malformed password in commands such as chpass or passwd.

Format string vulnerabilities in eeprom program in OpenBSD, NetBSD, and possibly other operating systems allows local attackers to gain root privileges.

security flaw

Format string vulnerability in startprinting() function of printjob.c in BSD-based lpr lpd package may allow local users to gain privileges via an improper syslog call that uses format strings from the checkremote() call.

kernel: Forwarding EAPOL from unauthenticated wifi client

An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients.

mail.local in NetBSD versions 6.0 through 6.0.6, 6.1 through 6.1.5, and 7.0 allows local users to change ownership of or append data to arbitrary files on the target system via a symlink attack on the user mailbox.

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.

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 memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects NetBSD 7.1 and possibly earlier versions.

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.

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 HZ module in the iconv implementation in FreeBSD 10.0 before p6 and NetBSD allows context-dependent attackers to cause a denial of service (NULL pointer dereference) via a crafted argument to the iconv_open function. NOTE: this issue was SPLIT per ADT2 due to different vulnerability types. CVE-2014-5384 is used for the NULL pointer dereference.

The VIQR module in the iconv implementation in FreeBSD 10.0 before p6 and NetBSD allows context-dependent attackers to cause a denial of service (out-of-bounds array access) via a crafted argument to the iconv_open function. NOTE: this issue was SPLIT from CVE-2014-3951 per ADT2 due to different vulnerability types.

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.
