IBM AIX 5.3.9

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 _tt_internal_realpath 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.

Multiple unspecified vulnerabilities in IBM AIX 5.2.0 through 6.1.2 allow local users to append data to arbitrary files, related to (1) rmsock and (2) rmsock64 not creating "secure log files."

at in bos.rte.cron on IBM AIX 5.2.0, 5.3.0 through 5.3.9, and 6.1.0 through 6.1.2 allows local users to read arbitrary files via unspecified vectors, related to failure to drop root privileges.
