DETAILED INFORMATION
I. DESCRIPTION
1. CVE-2014-3505
OpenSSL could allow remote attackers to cause a denial of service
(application crash) via crafted DTLS packets that trigger an error condition.
2. CVE-2014-3506
OpenSSL could allow remote attackers to cause a denial of service (memory
consumption) via crafted DTLS handshake messages that trigger memory
allocations corresponding to large length values.
3. CVE-2014-3507
OpenSSL could allow remote attackers to cause a denial of service
(memory consumption) via zero-length DTLS fragments that trigger improper
handling of the return value of insert function.
4. CVE-2014-3508
OpenSSL could allow context-dependent attackers to obtain sensitive information
from process stack memory by reading output from some functions when pretty
printing is used
5. CVE-2014-3509
OpenSSL could allow remote SSL servers to cause a denial of service
(memory overwrite and client application crash) or possibly have unspecified
impact by sending Elliptic Curve (EC) Supported Point Formats Extension data when
multithreading and session resumption are used
6. CVE-2014-3510
OpenSSL could allow remote DTLS servers to cause a denial of service
(NULL pointer dereference and client application crash) via a crafted
handshake message in conjunction with a (1) anonymous DH or
(2) anonymous ECDH ciphersuite.
7. CVE-2014-3511
OpenSSL could allow man-in-the middle attacker to force the use of TLS 1.0 by
triggering ClientHello message fragmentation in communication between a
client and server that both support later TLS versions, related to a
"protocol downgrade" issue
8. CVE-2014-3512
Openssl could allow remote attackers to cause a denial of service or possibly
have unspecified impact via an invalid SRP (1)g, (2)A or (3)B parameter
9. CVE-2014-5139
OpenSSL could allow SSL servers to cause a denial of service (NULL pointer
deference and client application crash) through a ServerHello message that
include an SRP ciphersuite without the required negotiation of that
ciphersuite with the client

AIX Fileset Lower Level Upper Level
------------------------------------------
openssl.base 1.0.1.500 1.0.1.511
B. CVE-2014-3505, CVE-2014-3506, CVE-2014-3507, CVE-2014-3508, CVE-2014-3510

openssl.base 0.9.8.401 0.9.8.2502
openssl.base 12.9.8.1100 12.9.8.2502
IV. SOLUTIONS
A. FIXES
Fix is available. The fix can be downloaded via ftp
from:
ftp://aix.software.ibm.com/aix/efixes/security/openssl_fix10.tar
The link above is to a tar file containing this signed
advisory, fix packages, and OpenSSL signatures for each package.
The fixes below include prerequisite checking. This will
enforce the correct mapping between the fixes and AIX
releases.
Note that the tar file contains Interim fixes that are based on OpenSSL version.
AIX Level Interim Fix (*.Z) Fileset Name
-------------------------------------------------------------------
5.3, 6.1, 7.1 101_fix.140902.epkg.Z openssl.base(1.0.1.511 version)
5.3, 6.1, 7.1 098_fix.140902.epkg.Z openssl.base(0.9.8.2502 version)
5.3, 6.1, 7.1 1298_fix.140902.epkg.Z openssl.base(12.9.8.2502 version)
VIOS Level Interim Fix (*.Z) Fileset Name
-------------------------------------------------------------------
2.2.* 101_fix.140902.epkg.Z openssl.base(1.0.1.511 version)
2.2.* 098_fix.140902.epkg.Z openssl.base(0.9.8.2502 version)
2.2.* 1298_fix.140902.epkg.Z openssl.base(12.9.8.2502 version)
To extract the fix from the tar file:
tar xvf openssl_fix10.tar
cd openssl_fix10
Verify you have retrieved the fix intact:
The checksums below were generated using the
"openssl dgst -sha256 file" command is the followng:
openssl dgst -sha256 filename
----------------------------------------------------------------------------------------------
4b5dcf19fbe1068b65b9ecc125d098fcf6f2077971e80c8da7bdfb2260554bd6 101_fix.140902.epkg.Z
834ff7e39d65c98eb7d96b877eab5c2f3ce9922d6ee5b8278358ae6b86d6ab87 098_fix.140902.epkg.Z
749536a5247176e8074ba1ec289426cbd4b484c9925ce17a66b411fad2e90841 1298_fix.140902.epkg.Z
These sums should match exactly. The OpenSSL signatures in the tar
file and on this advisory can also be used to verify the
integrity of the fixes. If the sums or signatures cannot be
confirmed, contact IBM AIX Security at
security-alert@austin.ibm.com and describe the discrepancy.
Published advisory OpenSSL signature file location:
http://aix.software.ibm.com/aix/efixes/security/openssl_advisory10.asc.sig
https://aix.software.ibm.com/aix/efixes/security/openssl_advisory10.asc.sig
ftp://aix.software.ibm.com/aix/efixes/security/openssl_advisory10.asc.sig
openssl dgst -sha1 -verify <pubkey_file> -signature <advisory_file>.sig <advisory_file>
openssl dgst -sha1 -verify <pubkey_file> -signature <ifix_file>.sig <ifix_file>
These fixes will also be part of the next filesets of OpenSSL versions 0.9.8.2503, 12.9.8.2503 and 1.0.1.512.
These filesets will be made available by 10th October 2014 and can be downloaded from -

B. FIX AND INTERIM FIX INSTALLATION
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 a fix installation:
installp -a -d fix_name -p all # where fix_name is the name of the
# fix package being previewed.
To install a fix package:
installp -a -d fix_name -X all # where fix_name is the name of the
# fix package being installed.
Interim fixes have had limited functional and regression
testing but not the full regression testing that takes place
for Service Packs; however, IBM does fully support them.
Interim fix management documentation can be found at:
http://www14.software.ibm.com/webapp/set2/sas/f/aix.efixmgmt/home.html
To preview an interim fix installation:
emgr -e ipkg_name -p # where ipkg_name is the name of the
# interim fix package being previewed.
To install an interim fix package:
emgr -e ipkg_name -X # where ipkg_name is the name of the
# interim fix package being installed.
V. WORKAROUNDS
No workarounds.
