Multiple vulnerabilities have been identified in IBM AIX, which could be exploited by local attackers to gain elevated privileges.
The first issue is caused by a buffer overflow error in the setuid root program "/usr/sbin/ndp", which could allow malicious users to execute arbitrary code with elevated privileges.
The second vulnerability is caused by a buffer overflow error in the privileged command "/usr/sbin/autoconf6", which could allow malicious users to gain elevated privileges if RBAC (role based access control) is in use and a user has the "aix.network.config.tcpip" authorization.
The third issue is caused by a design error in the privileged command "/usr/bin/enq", which could remove any file on the system if a print queue is defined in "/etc/qconfig".
The fourth vulnerability is caused by an unspecified error in the privileged command "/usr/bin/crontab", which could be exploited by a user who has the "aix.system.config.cron" authorization to gain elevated privileges.
