CERT Advisory CA-2002-07 Double Free Bug in zlib Compression Library
(Updated 3/29/2002)

IBM's   AIX   operating   system,   version   5.1,   ships  with  open
source-originated  zlib  that  is used with the Redhat Package Manager
(rpm)  to  install  applications  that  are  included in the AIX-Linux
Affinity Toolkit. zlib (libz.a) is a shared library in AIX. AIX 5.1 is
susceptible  to  the  described vulnerability. AIX 4.3.x does not ship
with zlib, but customers who install zlib and use it will be similarly
vulnerable.

An updated rpm.rte install image for AIX 5.1 can be obtained from:

 ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/INSTALLP/ppc/

Customers that have installed zlib from the AIX-Linux Affinity Toolkit
CD can obtain an updated zlib RPM from:

 ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/zlib/

CERT Advisory CA-2002-06 Vulnerabilities in Various Implementations of the
                         RADIUS Protocol

AIX is not vulnerable.
===============================================================================
===============================================================================
CERT Advisory CA-2002-03: Multiple Vulnerabilities in Many
Implementations of the Simple Network Management Protocol (SNMP)

The AIX operating system is susceptible to the vulnerabilities
tested for by the Oulu University PROTOS test suite for all
levels of AIX 4.3.x prior to level 4.3.3.51, and AIX 5.1 prior
to level 5.1.0.10. APARs were developed and made available last
year that closed the vulnerabilities looked for by the test suite.
For 4.3.x, the relevant APAR is #IY17630; for 5.1, the appropriate
APAR is #IY20943.

To see if your version and level of AIX is vulnerable, enter the
command:

  lslpp -l bos.net.tcp.client

If the "Level" stated is lower than those given above, your
system is vulnerable, and you are urged to apply the appropriate
APAR.

AIX versions prior to 4.3 are also vulnerable, but these versions
are no longer supported by IBM.
