Patches available for IBM AIX flaws

["NGSSoftware Insight Security Research" <nisr () nextgenss com>]

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:

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.
