Format string vulnerability in the _msgout function in rpc.pcnfsd in IBM AIX 6.1, 5.3, and earlier; IBM VIOS 2.1, 1.5, and earlier; NFS/ONCplus B.11.31_09 and earlier on HP HP-UX B.11.11, B.11.23, and B.11.31; and SGI IRIX 6.5 allows remote attackers to execute arbitrary code via an RPC request containing format string specifiers in an invalid directory name.

Buffer overflow in setsenv command in IBM AIX 4.3.x and earlier allows local users to execute arbitrary commands via a long "x=" argument.

Buffer overflow in digest command in IBM AIX 4.3.x and earlier allows local users to execute arbitrary commands.

Buffer overflow in enq command in IBM AIX 4.3.x and earlier may allow local users to execute arbitrary commands via a long -M argument.

Buffer overflow in setclock command in IBM AIX 4.3.x and earlier may allow local users to execute arbitrary commands via a long argument.

netstat in AIX 4.x.x does not properly restrict access to the -Zi option, which allows local users to clear network interface statistics and possibly hide evidence of unusual network activities.

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.

Vulnerability in AIX 3.2.x and 4.x allows local users to gain write access to files on locally or remotely mounted AIX filesystems.

named-xfer in AIX 4.1.5 and 4.2.1 allows members of the system group to overwrite system files to gain root access via the -f parameter and a malformed zone file.

The ToolTalk ttsession daemon uses weak RPC authentication, which allows a remote attacker to execute commands.
