Oracle Enterprise Manager Grid Control Multiple Vulnerabilities (July 2017 CPU) (httpoxy)

Synopsis :

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

Description :

The version of Oracle Enterprise Manager Grid Control installed on
the remote host is missing a security patch. It is, therefore,
affected by multiple vulnerabilities :

- A flaw exists in the Bouncy Castle Java library due to
improper validation of a point within the elliptic
curve. An unauthenticated, remote attacker can exploit
this to obtain private keys by using a series of
specially crafted elliptic curve Diffie-Hellman (ECDH)
key exchanges, also known as an 'invalid curve attack.'
(CVE-2015-7940)

- A flaw exists in the PathTools module for Perl in the
File::Spec::canonpath() function that is triggered as
strings are returned as untainted even when passing
tainted input. An unauthenticated, remote attacker can
exploit this to pass unvalidated user input to sensitive
or insecure areas. (CVE-2015-8607)

- An overflow condition exists in Perl in the MapPathA()
function due to improper validation of user-supplied
input. An unauthenticated, remote attacker can exploit
this to cause a denial of service condition or the
execution of arbitrary code. (CVE-2015-8608)

- A remote code execution vulnerability exists in the
Apache Struts component due to improper handling of
multithreaded access to an ActionForm instance. An
unauthenticated, remote attacker can exploit this, via a
specially crafted multipart request, to execute
arbitrary code or cause a denial of service condition.
(CVE-2016-1181)

- A flaw exists in Perl that is triggered during the
handling of variables that appear twice in the
environment (envp), causing the last value to appear in
%ENV, while getenv would return the first. An
unauthenticated, remote attacker can exploit this to
cause variables to be incorrectly propagated to
subprocesses, regardless of the protections offered by
taint checking. (CVE-2016-2381)

- A denial of service vulnerability exists in the Apache
Commons FileUpload component due to improper handling of
boundaries in content-type headers when handling file
upload requests. An unauthenticated, remote attacker can
exploit this to cause processes linked against the
library to become unresponsive. (CVE-2016-3092)

- A man-in-the-middle vulnerability exists in various
components, known as 'httpoxy', due to a failure to
properly resolve namespace conflicts in accordance with
RFC 3875 section 4.1.18. The HTTP_PROXY environment
variable is set based on untrusted user data in the
'Proxy' header of HTTP requests. The HTTP_PROXY
environment variable is used by some web client
libraries to specify a remote proxy server. An
unauthenticated, remote attacker can exploit this, via a
crafted 'Proxy' header in an HTTP request, to redirect
an application's internal HTTP traffic to an arbitrary
proxy server where it may be observed or manipulated.
(CVE-2016-5385, CVE-2016-5386, CVE-2016-5387,
CVE-2016-5388)

- A carry propagating error exists in the OpenSSL
component in the x86_64 Montgomery squaring
implementation that may cause the BN_mod_exp() function
to produce incorrect results. An unauthenticated, remote
attacker with sufficient resources can exploit this to
obtain sensitive information regarding private keys.
Moreover, the attacker would additionally need online
access to an unpatched system using the target private
key in a scenario with persistent DH parameters and a
private key that is shared between multiple clients. For
example, this can occur by default in OpenSSL DHE based
SSL/TLS cipher suites. (CVE-2017-3732)

- An unspecified flaw exists in the UI Framework component
that allows authenticated, remote attacker to have an
impact on integrity. (CVE-2017-10091)
