TITLE:
IBM AIX Multiple Privilege Escalation Vulnerabilities

SECUNIA ADVISORY ID:
SA32916

VERIFY ADVISORY:
http://secunia.com/advisories/32916/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
AIX 6.x
http://secunia.com/advisories/product/16995/

DESCRIPTION:
Some vulnerabilities have been reported in IBM AIX, which can be
exploited by malicious, local users to gain escalated privileges.

1) A boundary error in the "/usr/sbin/ndp" setuid root program can be
exploited to cause a buffer overflow.

Successful exploitation requires that the "netcd" daemon is running.


2) A boundary error in the privileged "/usr/sbin/autoconf6" command
can be exploited to cause a buffer overflow.

Successful exploitation of this vulnerability requires that RBAC is
used and that the attacker has the "aix.network.config.tcpip"
authorization.  

3) An error in the privileged "/usr/bin/enq" command can be exploited
to delete arbitrary files, if "/etc/qconfig" defines a print queue.

4) An error in the privileged "/usr/bin/crontab" command can be
exploited to gain escalated privileges. 

Successful exploitation of this vulnerability requires the
"aix.system.config.cron" authorization.

The vulnerabilities are reported in AIX version 6.1.

Apply fixes or APARs.
