David Litchfield of NGSSoftware has discovered a multiple high risk
vulnerabilities in IBM's AIX operating systems.
1) There is a buffer overflow in the malloc debug system that when exploited
can yeild root privileges.
2) There is a buffer overflow in muxatmd which is setuid root.
3) There is a buffer overflow in slocal which is setuid root.
4) There are arbitrary file data append issues in getShell and getCommand in
conjuction with specific settings in the malloc debug system.Both getShell
and getCommand are setuid root.
Issue 1 affects AIX versions 5.3.
Issue 2 affects AIX versions 5.3, 5.2 and 5.1.
Issue 3 affects AIX versions 5.3, 5.2 and 5.1.
Issue 4 affects AIX versions 5.3, 5.2 and 5.1.
IBM has developed patches for these issues:
http://www-03.ibm.com/servers/eserver/support/unixservers/aixfixes.html
Administrators are urged to install the patches as soon as possible. Whilst
these attacks are "local" by nature, AIX servers running Informix, DB2 and
Oracle can be targeted remotely via specific SQL queries.
