DESCRIPTION

A local attacker can use several AIX vulnerabilities in order to
elevate his privileges.

The netcd daemon uses the /usr/sbin/ndp suid root program. A local
attacker can generate a buffer overflow in ndp in order to elevate
his privileges. [grav:2/4; IZ35170, IZ35181, IZ35209]

A local attacker with the aix.network.config.tcpip autorisation
can use a buffer overflow of /usr/sbin/autoconf6 in order to
elevate his privileges. [grav:1/4; IZ30231, IZ34393, IZ34753]

When a print queue is defined in /etc/qconfig, a local attacker
can use /usr/bin/enq to delete a file. [grav:1/4; IZ33088,
IZ34481, IZ34785]

An attacker with the aix.system.config.cron privilege can use an
editor with elevated privileges via /usr/bin/crontab. [grav:1/4;
IZ30248, IZ34478, IZ34783]
