rpc.walld (wall daemon) for Solaris 2.6 through 9 allows local users to send messages to logged on users that appear to come from arbitrary user IDs by closing stderr before executing wall, then supplying a spoofed from header.
The libthread library (libthread.so.1) for Solaris 2.5.1 through 8 allows local users to cause a denial of service (hang) of an application that uses libthread by causing the application to wait for a certain mutex.
Solaris 2.5.1 through 9 allows local users to cause a denial of service (kernel panic) by setting the sdstruiowrq variable in the struioget function to null, which triggers a null dereference.
The finger daemon (in.fingerd) in Sun Solaris 2.5 through 8 and SunOS 5.5 through 5.8 allows remote attackers to list all accounts on a host by typing finger 'a b c d e f g h'@host.
Solaris arp allows local users to read files via the -f parameter, which lists lines in the file that do not parse properly.
Solaris chkperm allows local users to read files owned by bin via the VMSYS environmental variable and a symlink attack.
Solaris ff.core allows local users to modify files.
ping in Solaris 2.3 through 2.6 allows local users to cause a denial of service (crash) via a ping request to a multicast address through the loopback interface, e.g. via ping -i.
The access permissions for a UNIX domain socket are ignored in Solaris 2.x and SunOS 4.x, and other BSD-based operating systems before 4.4, which could allow local users to connect to the socket and possibly disrupt or control the operations of the program using that socket.
