Windows 95 uses weak encryption for the password list (.pwl) file used when password caching is enabled, which allows local users to gain privileges by decrypting the passwords.

dxconsole in DEC OSF/1 3.2C and earlier allows local users to read arbitrary files by specifying the file with the -file parameter.

lpr on SunOS 4.1.1, BSD 4.3, A/UX 2.0.1, and other BSD-based operating systems allows local users to create or overwrite arbitrary files via a symlink attack that is triggered after invoking lpr 1000 times.

Kabsoftware Lydia utility uses weak encryption to store user passwords in the lydia.ini file, which allows local users to easily decrypt the passwords and gain privileges.

Cisco PIX Private Link 4.1.6 and earlier does not properly process certain commands in the configuration file, which reduces the effective key length of the DES key to 48 bits instead of 56 bits, which makes it easier for an attacker to find the proper key via a brute force attack.

Kerberos 4 allows remote attackers to obtain sensitive information via a malformed UDP packet that generates an error string that inadvertently includes the realm name and the last user.

Vulnerability in BSD Telnet client with encryption and Kerberos 4 authentication allows remote attackers to decrypt the session via sniffing.

Microsoft NetMeeting 2.1 allows one client to read the contents of another client's clipboard via a CTRL-C in the chat box when the box is empty.

Buffer overflow in kscreensaver in KDE klock allows local users to gain root privileges via a long HOME environmental variable.

sort creates temporary files and follows symbolic links, which allows local users to modify arbitrary files that are writable by the user running sort, as observed in updatedb and other programs that use sort.

Buffer overflow in Internet Explorer 4.01 and earlier allows remote attackers to execute arbitrary commands via a long URL with the "mk:" protocol, aka the "MK Overrun security issue."

Buffer overflow in the Window.External function in the JScript Scripting Engine in Internet Explorer 4.01 SP1 and earlier allows remote attackers to execute arbitrary commands via a malicious web page.

tin 1.40 creates the .tin directory with insecure permissions, which allows local users to read passwords from the .inputhistory file.

UNIX news readers tin and rtin create the /tmp/.tin_log file with insecure permissions and follow symlinks, which allows attackers to modify the permissions of files writable by the user via a symlink attack.

The default configuration of NCSA Telnet package for Macintosh and PC enables FTP, even though it does not include an "ftp=yes" line, which allows remote attackers to read and modify arbitrary files.

Buffer overflow in chfn command in HP-UX 9.X through 10.20 allows local users to gain privileges via a long command line argument.

Vulnerability in chsh command in HP-UX 9.X through 10.20 allows local users to gain privileges.

Internet Explorer 4 treats a 32-bit number ("dotless IP address") in the a URL as the hostname instead of an IP address, which causes IE to apply Local Intranet Zone settings to the resulting web page, allowing remote malicious web servers to conduct unauthorized activities by using URLs that contain the dotless IP address for their server.

Novell 5 and earlier, when running over IPX with a packet signature level less than 3, allows remote attackers to gain administrator privileges by spoofing the MAC address in IPC fragmented packets that make NetWare Core Protocol (NCP) calls.

SSH 1.2.25, 1.2.23, and other versions, when used in in CBC (Cipher Block Chaining) or CFB (Cipher Feedback 64 bits) modes, allows remote attackers to insert arbitrary data into an existing stream between an SSH client and server by using a known plaintext attack and computing a valid CRC-32 checksum for the packet, aka the "SSH insertion attack."
