AS/400 Telnet 5250 terminal emulation clients, as implemented by (1) IBM client access, (2) Bosanova, (3) PowerTerm, (4) Mochasoft, and possibly other emulations, allows malicious AS/400 servers to execute arbitrary commands via a STRPCO (Start PC Organizer) command followed by STRPCCMD (Start PC command), as demonstrated by creating a backdoor account using REXEC.

Buffer overflow in the slc_add_reply function in various BSD-based Telnet clients, when handling LINEMODE suboptions, allows remote attackers to execute arbitrary code via a reply with a large number of Set Local Character (SLC) commands.

id3_utf16_deserialize() in utf16.c in libid3tag through 0.15.1b misparses ID3v2 tags encoded in UTF-16 with an odd number of bytes, triggering an endless loop allocating memory until an OOM condition is reached, leading to denial-of-service (DoS).

FreeRADIUS RADIUS server allows remote attackers to cause a denial of service (CPU consumption) via a flood of Access-Request packets.

Buffer overflow in efax 0.9 and earlier, when installed setuid root, allows local users to execute arbitrary code via a long -x argument.

efax 0.9 and earlier, when installed setuid root, allows local users to read arbitrary files via the -d option, which prints the contents of the file in a warning message.

strace allows local users to read arbitrary files via memory mapped file names.

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.

Race condition in xterm allows local users to modify arbitrary files via the logging option.

ypserv allows local administrators to modify password tables.

ypserv allows a local user to modify the GECOS and login shells of other users.

Lynx WWW client allows a remote attacker to specify command-line parameters which Lynx uses when calling external programs to handle certain protocols, e.g. telnet.

The ugidd RPC interface by design allows remote attackers to enumerate valid usernames by specifying arbitrary UIDs that ugidd maps to local user and group names.

A version of finger is running that exposes valid user information to any entity on the network.

ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.

A race condition in how procmail handles .procmailrc files allows a local user to read arbitrary files available to the user who is running procmail.
