CERT Advisory CA-2002-23 Multiple Vulnerabilities In OpenSSL

There are four remotely exploitable buffer overflows in OpenSSL. There
are  also  encoding  problems  in  the  ASN.1 library used by OpenSSL.
Several of these vulnerabilities could be used by a remote attacker to
execute  arbitrary  code  on  the  target system. All could be used to
create denial of service.

IBM's AIX operating system does not ship with OpenSSL; however, OpenSSL is
available for installation on AIX via the Linux Affinity Toolkit. The
version included on the Toolkit CD is vulnerable to the issues discussed
here as will as the version of OpenSSL available for downloading from the
IBM Linux Affinity website. Anyone running this version is advised to
upgrade to the new version available from the website. This will be
available within the next few days and can be downloaded from

             http://www6.software.ibm.com/dl/aixtbx/aixtbx-p

This site contains Linux Affinity applications using cryptographic
algorithms. New users to this site are asked to register first.
