Indigo Magic System Tour in the SGI system tour package (systour) for IRIX 5.x through 6.3 allows local users to gain root privileges via a Trojan horse .exitops program, which is called by the inst command that is executed by the RemoveSystemTour program.
Buffer overflow in lpr, as used in BSD-based systems including Linux, allows local users to execute arbitrary code as root via a long -C (classification) command line option.
Denial of service when an attacker sends many SYN packets to create multiple connections without ever sending an ACK to complete the connection, aka SYN flood.
Transarc DCE Distributed File System (DFS) 1.1 for Solaris 2.4 and 2.5 does not properly initialize the grouplist for users who belong to a large number of groups, which could allow those users to gain access to resources that are protected by DFS.
(1) bash before 1.14.7, and (2) tcsh 6.05 allow local users to gain privileges via directory names that contain shell metacharacters (` back-tick), which can cause the commands enclosed in the directory name to be executed when the shell expands filenames using the \w option in the PS1 variable.
Solaris 2.4 before kernel jumbo patch -35 allows set-gid programs to dump core even if the real user id is not in the set-gid group, which allows local users to overwrite or create files at higher privileges by causing a core dump, e.g. through dmesg.
cpio on FreeBSD 2.1.0, Debian GNU/Linux 3.0, and possibly other operating systems, uses a 0 umask when creating files using the -O (archive) or -F options, which creates the files with mode 0666 and allows local users to read or overwrite those files.
A design flaw in the Z-Modem protocol allows the remote sender of a file to execute arbitrary programs on the client, as implemented in rz in the rzsz module of FreeBSD before 2.1.5, and possibly other programs.
The convert.bas program in the Novell web server allows a remote attackers to read any file on the system that is internally accessible by the web server.
Vulnerability in a kernel error handling routine in SCO OpenServer 5.0.2 and earlier, and SCO Internet FastStart 1.0, allows local users to gain root privileges.
nettune in HP-UX 10.01 and 10.00 is installed setuid root, which allows local users to cause a denial of service by modifying critical networking configuration information.
Perl, sh, csh, or other shell interpreters are installed in the cgi-bin directory on a WWW site, which allows remote attackers to execute arbitrary commands.
Vulnerability in union file system in FreeBSD 2.2 and earlier, and possibly other operating systems, allows local users to cause a denial of service (system reload) via a series of certain mount_union commands.
