Oracle Secure Global Desktop Multiple Vulnerabilities (July 2016 CPU)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

An application installed on the remote host is affected by multiple
vulnerabilities.

Description :

The version of Oracle Secure Global Desktop installed on the remote
host is 4.63, 4.71, or 5.2 and is missing a security patch from the
July 2016 Critical Patch Update (CPU). It is, therefore, affected by
the following vulnerabilities :

- An integer overflow condition exists in the X Server
subcomponent in the read_packet() function due to
improper validation of user-supplied input when
calculating the amount of memory required to handle
returned data. A remote attacker can exploit this to
cause a denial of service condition or the execution of
arbitrary code. Note that this vulnerability only
affects versions 4.71 and 5.2. (CVE-2013-2064)

- A carry propagating flaw exists in the OpenSSL
subcomponent in the x86_64 Montgomery squaring
implementation that may cause the BN_mod_exp() function
to produce incorrect results. An attacker can exploit
this to obtain sensitive information regarding private
keys. (CVE-2015-3193)

- A NULL pointer dereference flaw exists in the OpenSSL
subcomponent in file rsa_ameth.c when handling ASN.1
signatures that use the RSA PSS algorithm but are
missing a mask generation function parameter. A remote
attacker can exploit this to cause the signature
verification routine to crash, leading to a denial of
service. (CVE-2015-3194)

- A key disclosure vulnerability exists in the OpenSSL
subcomponent due to improper handling of cache-bank
conflicts on the Intel Sandy-bridge microarchitecture.
An attacker can exploit this to gain access to RSA key
information. (CVE-2016-0702)

- A NULL pointer dereference flaw exists in the OpenSSL
subcomponent in the BN_hex2bn() and BN_dec2bn()
functions. A remote attacker can exploit this to trigger
a heap corruption, resulting in the execution of
arbitrary code. (CVE-2016-0797)

- Multiple memory corruption issues exist in the OpenSSL
subcomponent that allow a remote attacker to cause a
denial of service condition or the execution of
arbitrary code. (CVE-2016-0799)

- A heap buffer overflow condition exists in the OpenSSL
subcomponent in the EVP_EncodeUpdate() function within
file crypto/evp/encode.c that is triggered when handling
a large amount of input data. An unauthenticated, remote
attacker can exploit this to cause a denial of service
condition. (CVE-2016-2105)

- Multiple flaws exist in the OpenSSL subcomponent in the
aesni_cbc_hmac_sha1_cipher() function in file
crypto/evp/e_aes_cbc_hmac_sha1.c and the
aesni_cbc_hmac_sha256_cipher() function in file
crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered
when the connection uses an AES-CBC cipher and AES-NI
is supported by the server. A man-in-the-middle attacker
can exploit these to conduct a padding oracle attack,
resulting in the ability to decrypt the network traffic.
(CVE-2016-2107)

- An unspecified flaw exists in the OpenSSL subcomponent
that allows a remote attacker to execute arbitrary
code. (CVE-2016-3613)
