"The version of OpenSSL running on the remote host is affected by the
following vulnerabilities :

  - The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0
    and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and
    other products, do not properly consider timing side-
    channel attacks on a MAC check requirement during the
    processing of malformed CBC padding, which allows
    remote attackers to conduct distinguishing attacks and
    plaintext-recovery attacks via statistical analysis of
    timing data for crafted packets, aka the 'Lucky
    Thirteen' issue. (CVE-2013-0169)

  - OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1
    before 1.0.1d does not properly perform signature
    verification for OCSP responses, which allows remote
    attackers to cause a denial of service (NULL pointer
    dereference and application crash) via an invalid key.
    (CVE-2013-0166)");

To extract the fixes from the tar file :

  zcat openssl-0.9.8.2500.tar.Z | tar xvf -
  or
  zcat openssl-fips-12.9.8.2500.tar.Z | tar xvf -

IMPORTANT : If possible, it is recommended that a mksysb backup of
the system be created.  Verify it is both bootable and readable
before proceeding.

To preview the fix installation :

  installp -apYd . openssl

To install the fix package :

  installp -aXYd . openssl");
