IBM AIX 6.1.1

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.

nfs.ext in IBM AIX 5.3.x through 5.3.9 and 6.1.0 through 6.1.2 does not properly use the nfs_portmon setting, which allows remote attackers to bypass intended access restrictions for NFSv4 shares via unspecified vectors.

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.

A software logic bug creates a vulnerability in an AIX 6.1, 7.1, and 7.2 daemon which could allow a user with root privileges on one system, to obtain root access on another machine. IBM X-force ID: 138117.

gssd in IBM AIX 5.3.x through 5.3.9 and 6.1.0 through 6.1.2 does not properly handle the NFSv4 Kerberos credential cache, which allows local users to bypass intended access restrictions for Kerberized NFSv4 shares via unspecified vectors.

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."

Buffer overflow in ndp in IBM AIX 6.1.0 through 6.1.2, when the netcd daemon is running, allows local users to gain privileges via unspecified vectors.

crontab in bos.rte.cron in IBM AIX 6.1.0 through 6.1.2 allows local users with aix.system.config.cron authorization to gain privileges by launching an editor.

enq in bos.rte.printers in IBM AIX 6.1.0 through 6.1.2, when a print queue is defined in /etc/qconfig, allows local users to delete arbitrary files via unspecified vectors.

Buffer overflow in autoconf6 in IBM AIX 6.1.0 through 6.1.2, when Role-Based Access Control is enabled, allows local users with aix.network.config.tcpip authorization to gain privileges via unspecified vectors.

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.
