A buffer overrun vulnerability exists in the Xsun X11 server, as shipped as part of Solaris 7 and 8 from Sun Microsystems. By supplying a long argument to the -dev option (normally used to set the output device), it is possible to execute arbitrary code with setgid root permissions. This can be further leveraged to gain root privileges, resulting in machine compromise.
PostgreSQL stores passwords for database users in a binary file called pg_shadow. This file is readable by root and the postgres user. Unfortunately, these passwords are stored in cleartext form and can be obtained if a user with read access to the file runs strings on it.
A vulnerability exists in the handling of the -r option to the lpset program, as included in Solaris 7 from Sun Microsystems. The -r option is undocumented. As such, its use in unknown. However, when supplied a well crafted buffer containing executable code, it is possible to execute arbitrary commands as root.

Certain versions of Zone Labs personal Firewall have a vulnerability which allows malicious users to port scan the firewall without being detected. In particular if the port scan originates from source port 67 on the attacking host the ZoneAlarm fails to register the attack.
CVS stands for Concurrent Versions Software and is an open-source package designed to allow multiple developers to work concurrently on a single source tree, recording changes and controlling versions. It is possible to cause a denial of service for users of CVS due to predictable temporary filenames. CVS uses locking directories in /tmp and combines the static string 'cvs-serv' with the process ID to use as filenames. This is trivial to guess for an attacker, and since /tmp is world writeable, directories can be created with predicted names. CVS drops root priviliges, so these directories cannot be overwritten and every session for which a locking directory has been already created (by the attacker) will be broken. The following perl script will create many directories in /tmp with incrementing pids: #!/usr/bin/perl $min=400; $max=4000; for ($x=$min;$x<=$max;$x++) { open CVSTMP, ">>/tmp/cvs-serv$x" or die "/tmp/cvs-serv$x: $!"; chmod 0600, "/tmp/cvs-serv$x"; close CVSTMP; }
A vulnerability exists in a number of pop3 daemon implementations, having to do with their creation of lock files. Affected include Qualcomm's qpopper, and the popd included as part of the imap-4 rpm from RedHat. Lockfiles in both implementation are created with consistent local file names; the RedHat popd in /tmp, with a fairly random name (albeit consistent for a given user), and in the mail spool directory, with the user name prepended by a "." and appended with ".pop". Creation of either of these files will prevent the popd user from being able to establish a connection to retrieve their mail. The FreeBSD port of imap-uw contains this vulnerability. It is not, however, included as a standard part of a FreeBSD install.
A vulnerability exists in the server portion of version 0.4 of the LCDProc package. Several remote buffer overflows exist that could allow a remote attacker to corrupt memory and execute arbitrary code. It is possible to exploit this conditions to execute code with the privileges of the user LCDProc is running as.
A vulnerability exists in SuSE Linux, version 6.3 and prior, that can allow arbitrary users to delete any file on the system. If the MAX_DAYS_IN_TMP variable is set in /etc/rc.config to be larger than 0, any local user can remove any file on the system. This is due to a flaw in /etc/cron.daily/aaa_base in SuSE 6.3, or /root/bin/cron.daily in older versions. It has been reported that only files in the root directory (/) can be removed. Previously, it was thought arbitrary files anywhere on the filesystem could be removed.
