Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow,…

The lreply function in wu-ftpd 2.6.0 and earlier does not properly cleanse an untrusted format string, which allows remote attackers to execute arbitrary commands via the SITE EXEC command.

wu-ftpd 2.6.1 allows remote attackers to execute arbitrary commands via a "~{" argument to commands such as CWD, which is not properly handled by the glob function (ftpglob).

A system is running a version of software that was replaced with a Trojan Horse at one of its distribution points, such as (1) TCP Wrappers 7.6, (2) util-linux 2.9g, (3) wuarchive ftpd (wuftpd) 2.2 and 2.1f, (4) IRC client (ircII) ircII 2.2.9, (5) OpenSSH 3.4p1, or (6) Sendmail…

Buffer overflow in ProFTPD, wu-ftpd, and beroftpd allows remote attackers to gain root access via a series of MKD and CWD commands that create nested directories.

Buffer overflow in War FTPd 1.6x allows users to cause a denial of service via long MKD and CWD commands.

Buffer overflow in WU-FTPD and related FTP servers allows remote attackers to gain root privileges via macro variables in a message file.

The wu_fnmatch function in wu_fnmatch.c in wu-ftpd 2.6.1 and 2.6.2 allows remote attackers to cause a denial of service (CPU exhaustion by recursion) via a glob pattern with a large number of * (wildcard) characters, as demonstrated using the dir command.

ls in the fileutils or coreutils packages allows local users to consume a large amount of memory via a large -w value, which can be remotely exploited via applications that use ls, such as wu-ftpd.

Format string vulnerability in wu-ftp 2.6.1 and earlier, when running with debug mode enabled, allows remote attackers to execute arbitrary commands via a malformed argument that is recorded in a PASV port assignment.

Buffer overflow in the skey_challenge function in ftpd.c for wu-ftp daemon (wu-ftpd) 2.6.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a s/key (SKEY) request with a long name.

ftpd.c in (1) wu-ftpd 2.4.2 and (2) ftpd in HP HP-UX B.11.11 assigns uid 0 to the FTP client in certain operating-system misconfigurations in which PAM authentication can succeed even though no passwd entry is available for a user, which allows remote attackers to gain…

ftpd, as used by Gentoo and Debian Linux, sets the gid to the effective uid instead of the effective group id before executing /bin/ls, which allows remote authenticated users to list arbitrary directories with the privileges of gid 0 and possibly enable additional attack…

ftpd.c in wu-ftpd 2.6.2, when running on "operating systems that only allow one non-connected socket bound to the same local address," does not close failed connections, which allows remote attackers to cause a denial of service.

Vulnerability in wu-ftpd 2.6.0, and possibly earlier versions, which is unrelated to the ftpglob bug described in CVE-2001-0550.

Denial of service in WU-FTPD via the SITE NEWER command, which does not free memory properly.

Buffer overflow in WU-FTPD and related FTP servers allows remote attackers to gain root privileges via MAPPING_CHDIR.

wu-ftpd 2.4 FTP server does not properly drop privileges when an ABOR (abort file transfer) command is executed during a file transfer, which causes a signal to be handled incorrectly and allows local and possibly remote attackers to read arbitrary files.

PASV core dump in wu-ftpd daemon when attacker uses a QUOTE PASV command after specifying a username and password.
