Caldera Openlinux 2.3

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.

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

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

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.

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.

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.

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.

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