attacker can exploit this to free already freed memory,
resulting in an unspecified impact on confidentiality,
integrity, and availability. (CVE-2016-8619)

- An out-of-bounds access error exists in cURL in file
tool_urlglob.c within the globbing feature. An
unauthenticated, remote attacker can exploit this to
disclose memory contents or execute arbitrary code.
(CVE-2016-8620)

- An out-of-bounds error exists in cURL in the parsedate()
function within file lib/parsedate.c when handling
dates. An unauthenticated, remote attacker can exploit
this to disclose memory contents or cause a denial of
service condition. (CVE-2016-8621)

- An integer truncation error exists in cURL in the
curl_easy_unescape() function within file lib/escape.c

unauthenticated, remote attacker can exploit this to
disclose memory contents. (CVE-2016-8623)

- A flaw exists in cURL in the parseurlandfillconn()
function within file lib/url.c when parsing the
authority component of a URL with the host name part
ending in a '#' character. An unauthenticated, remote
attacker can exploit this to establish a connection to
a different host than intended. (CVE-2016-8624)

- A flaw exists in cURL within International Domain Names
(IDNA) handling when translating domain names to puny
code for DNS resolving due to using the outdated IDNA
2003 standard instead of the IDNA 2008 standard, which
can result in incorrect translation of a domain name.
An unauthenticated, remote attacker can exploit this to
cause network traffic to be redirected to a different
host than intended. (CVE-2016-8625)

- A flaw exists in Apache Tomcat within the
catalina/mbeans/JmxRemoteLifecycleListener.java class
that is triggered during the deserialization of Java
objects. An unauthenticated, remote attacker can exploit
this to execute arbitrary code. (CVE-2016-8735)

- A flaw exists in the Web Server component (Apache HTTP
Server) when handling whitespace patterns in User-Agent
headers. An authenticated, remote attacker can exploit
this, via a specially crafted User-Agent header, to
cause incorrect processing of sequences of requests,
resulting in incorrectly interpreting responses,
polluting the cache, or disclosing content from one
request to a second downstream user-agent.
(CVE-2016-8743)

- A NULL pointer dereference flaw exists within file
ssl/statem/statem_clnt.c when handling parameters for
the DHE or ECDHE key exchanges. An unauthenticated,
remote attacker can exploit this, via specially crafted
parameters, to cause a denial of service condition.
(CVE-2017-3730)

- A out-of-bounds read error exists exists in the Core
subcomponent, specifically in OpenSSL, when handling
packets using the CHACHA20/POLY1305 or RC4-MD5 ciphers.
An unauthenticated, remote attacker can exploit this,
via specially crafted truncated packets, to cause a
denial of service condition. (CVE-2017-3731)

- A carry propagating error exists 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. Note that this issue
is very similar to CVE-2015-3193. 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)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.
