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.11.3109 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.

Stack-based buffer overflow in libcsa.a (aka the calendar daemon library) in IBM AIX 5.x through 5.3.10 and 6.x through 6.1.3, and VIOS 2.1 and earlier, allows remote attackers to execute arbitrary code via a long XDR string in the first argument to procedure 21 of rpc.cmsd.

Stack-based buffer overflow in the ttinternalrealpath function in the ToolTalk library (libtt.a) in IBM AIX 5.2.0, 5.3.0, 5.3.7 through 5.3.10, and 6.1.0 through 6.1.3, when the rpc.ttdbserver daemon is enabled in /etc/inetd.conf, allows remote attackers to execute arbitrary code via a long XDR-encoded ASCII string to remote procedure 15.

Unspecified vulnerability in utape in IBM AIX 5.2.0 and 5.3.0 allows attackers to execute arbitrary commands and overwrite arbitrary files via unspecified vectors.
