Jolt ICMP attack causes a denial of service in Windows 95 and Windows NT systems.

IPFilter 3.4.16 and earlier does not include sufficient session information in its cache, which allows remote attackers to bypass access restrictions by sending fragmented packets to a restricted port after sending unfragmented packets to an unrestricted port.

time server daemon timed allows remote attackers to cause a denial of service via malformed packets.

Sysinstall in FreeBSD 2.2.1 and earlier, when configuring anonymous FTP, creates the ftp user without a password and with /bin/date as the shell, which could allow attackers to gain access to certain system resources.

Race condition in the UFS and EXT2FS file systems in FreeBSD 4.2 and earlier, and possibly other operating systems, makes deleted data available to user processes before it is zeroed out, which allows a local user to access otherwise restricted information.

sort in FreeBSD 4.1.1 and earlier, and possibly other operating systems, uses predictable temporary file names and does not properly handle when the temporary file already exists, which causes sort to crash and possibly impacts security-sensitive scripts.

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.

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

Listening TCP ports are sequentially allocated, allowing spoofing attacks.

Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3.

Buffer overflow in dc20ctrl before 0.4_1 in FreeBSD, and possibly other operating systems, allows local users to gain privileges.

Pine before version 3.94 allows local users to gain privileges via a symlink attack on a lockfile that is created when a user receives new mail.

inetd ident server in FreeBSD 4.x and earlier does not properly set group permissions, which allows remote attackers to read the first 16 bytes of files that are accessible by the wheel group.

FreeBSD kernel 5.4-STABLE and 6.0 does not completely initialize a buffer before making it available to userland, which could allow local users to read portions of kernel memory.

ipfw and ip6fw in FreeBSD 4.2 and earlier allows remote attackers to bypass access restrictions by setting the ECE flag in a TCP packet, which makes the packet appear to be part of an established connection.

xsoldier program allows local users to gain root access via a long argument.

The open() function in FreeBSD allows local attackers to write to arbitrary files.

Integer overflow in IEEE 802.11 network subsystem (ieee80211_ioctl.c) in FreeBSD before 6.0-STABLE, while scanning for wireless networks, allows remote attackers to execute arbitrary code by broadcasting crafted (1) beacon or (2) probe response frames.

The ispell_op function in ee on FreeBSD 4.10 to 6.0 uses predictable filenames and does not confirm which file is being written, which allows local users to overwrite arbitrary files via a symlink attack when ee invokes ispell.

security flaw

Zope before 2.2.4 does not properly compute local roles, which could allow users to bypass specified access restrictions and gain privileges.
