script_set_attribute(attribute:"description", value:
"The version of IBM BigFix Remote Control running on the remote host is
prior to 9.1.3. It is, therefore, affected by the multiple
vulnerabilities :
- Multiple integer overflow conditions exist in the
bundled version of OpenSSL in files s3_srvr.c,
ssl_sess.c, and t1_lib.c due to improper use of pointer
arithmetic for heap-buffer boundary checks. An
unauthenticated, remote attacker can exploit this to
cause a denial of service. (CVE-2016-2177)
- An information disclosure vulnerability exists in the
bundled version of OpenSSL in the dsa_sign_setup()
function in dsa_ossl.c due to a failure to properly
ensure the use of constant-time operations. An
unauthenticated, remote attacker can exploit this, via a
timing side-channel attack, to disclose DSA key
information. (CVE-2016-2178)
- A vulnerability exists, known as SWEET32, in the bundled
version of OpenSSL in the 3DES and Blowfish algorithms
due to the use of weak 64-bit block ciphers by default.
A man-in-the-middle attacker who has sufficient
resources can exploit this vulnerability, via a
'birthday' attack, to detect a collision that leaks the
XOR between the fixed secret and a known plaintext,
allowing the disclosure of the secret text, such as
secure HTTPS cookies, and possibly resulting in the
hijacking of an authenticated session. (CVE-2016-2183)
- An information disclosure vulnerability exists due to
the inclusion of sensitive information in error logs. An
authenticated, remote attacker can exploit this to
disclose information. (CVE-2016-2928)
- An information disclosure vulnerability exists due to
the transmission of information in cleartext. A
man-in-the-middle attacker can exploit this to disclose
sensitive information. (CVE-2016-2931)
- An unspecified flaw exists that allows an
unauthenticated, remote attacker to inject arbitrary XML
content. (CVE-2016-2932)
- An information disclosure vulnerability exists due to a
flaw that allows traversing outside of a restricted
path. An authenticated, remote attacker can exploit
this, via a specially crafted request, to disclose
arbitrary files. (CVE-2016-2933)
- A cross-site scripting (XSS) vulnerability exists due to
improper validation of user-supplied input. An
unauthenticated, remote attacker can exploit this, via a
specially crafted request, to execute arbitrary script
code in a user's browser session. (CVE-2016-2934)
- An unspecified flaw exists that allows an
unauthenticated, remote attacker to submit invalid HTTP
requests, resulting in a denial of service condition for
the broker application. (CVE-2016-2935)
- An information disclosure vulnerability exists due to
the storage of information in log files in plaintext. A
local attacker can exploit this to disclose sensitive
information. (CVE-2016-2943)
- A flaw exists in the bundled version of OpenSSL in the
ssl_parse_clienthello_tlsext() function in t1_lib.c due
to improper handling of overly large OCSP Status Request
extensions from clients. An unauthenticated, remote
attacker can exploit this, via large OCSP Status Request
extensions, to exhaust memory resources, resulting in a
denial of service condition. (CVE-2016-6304)
- An out-of-bounds read error exists the bundled version
of OpenSSL in the certificate parser that allows an
unauthenticated, remote attacker to cause a denial of
service via crafted certificate operations.
(CVE-2016-6306)
Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
