Caldera » Openlinux : Security Vulnerabilities, CVEs,

The getdbm procedure in ypxfrd allows local users to read arbitrary files, and remote attackers to read databases outside /var/yp, via a directory traversal and symlink attack on the domain and map arguments.

Linux kernel 2.0, 2.2 and 2.4 with syncookies enabled allows remote attackers to bypass firewall rules by brute force guessing the cookie.

A configuration error in the libdb1 package in OpenLinux 3.1 uses insecure versions of the snprintf and vsnprintf functions, which could allow local or remote users to exploit those functions with a buffer overflow.

Multiple shell programs on various Unix systems, including (1) tcsh, (2) csh, (3) sh, and (4) bash, follow symlinks when processing << redirects (aka here-documents or in-here documents), which allows local users to overwrite files of other users via a symlink attack.

Format string vulnerability in use_syslog() function in LPRng 3.6.24 allows remote attackers to execute arbitrary commands.

Some telnet clients allow remote telnet servers to request environment variables from the client that may contain sensitive information, or remote web servers to obtain the information via a telnet: URL.

Some functions that implement the locale subsystem on Unix do not properly cleanse user-injected format strings, which allows local attackers to execute arbitrary commands via functions such as gettext and catopen.

makewhatis in Linux man package allows local users to overwrite files via a symlink attack.

Linux gpm program allows local users to cause a denial of service by flooding the /dev/gpmctl device with STREAM sockets.

The KApplication class in the KDE 1.1.2 configuration file management capability allows local users to overwrite arbitrary files.

Buffer overflow in the XDMCP parsing code of GNOME gdm, KDE kdm, and wdm allows remote attackers to execute arbitrary commands or cause a denial of service via a long FORWARD_QUERY request.

Buffer overflow in fdmount on Linux systems allows local users in the "floppy" group to execute arbitrary commands via a long mountpoint parameter.

The default configuration of kdm in Caldera and Mandrake Linux, and possibly other distributions, allows XDMCP connections from any host, which allows remote attackers to obtain sensitive information or bypass additional access restrictions.

Vulnerability in Caldera rmt command in the dump package 0.4b4 allows a local user to gain root privileges.

The debug option in Caldera Linux smail allows remote attackers to execute commands via shell metacharacters in the -D option for the rmail command.

The IDENT server in Caldera Linux 2.3 creates multiple threads for each IDENT request, which allows remote attackers to cause a denial of service.

Buffer overflow in Linux mount and umount allows local users to gain root privileges via a long relative pathname.

The default installation of Caldera OpenLinux 2.3 includes the CGI program rpm_query, which allows remote attackers to determine what packages are installed on the system.

Samba 1.9.18 inadvertently includes a prototype application, wsmbconf, which is installed with incorrect permissions including the setgid bit, which allows local users to read and write files and possibly gain privileges via bugs in the program.

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 macro variables in a message file.

Buffer overflow in Vixie cron allows local users to gain root access via a long MAILTO environment variable in a crontab file.

Vixie Cron on Linux systems allows local users to set parameters of sendmail commands via the MAILTO environmental variable.

The KDE klock program allows local users to unlock a session using malformed input.

A vulnerability in Caldera Open Administration System (COAS) allows the /etc/shadow password file to be made world-readable.
