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)

  - A flaw exists in the Core subcomponent, specifically in     the libcurl library, due to improper validation of TLS     certificates. An authenticated, remote attacker with the     ability to intercept network traffic can exploit this     issue to disclose or manipulate transmitted data by     spoofing the TLS/SSL server using a certificate that     appears valid. Note that this issue only affects     versions 5.2 and 5.3. (CVE-2016-3739)

  - A flaw exists in cURL and libcurl when loading dynamic     link library (DLL) files security.dll, secur32.dll, or     ws2_32.dll due searching an insecure path which may not     be trusted or under user control.

    (CVE-2016-5421)

  - A flaw exists in the tls_decrypt_ticket() function     in t1_lib.c due to improper handling of ticket HMAC     digests. An unauthenticated, remote attacker can exploit     this, via a ticket that is too short, to crash the     process, resulting in a denial of service.
    (CVE-2016-6302)

  - An integer overflow condition exists in the     MDC2_Update() function in mdc2dgst.c due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a heap-based     buffer overflow, resulting in a denial of service     condition or possibly the execution of arbitrary code.
    (CVE-2016-6303)

  - A flaw exists in the ssl_parse_clienthello_tlsext()     function in t1_lib.c due to improper handling of overly     large OCSP Status Request extensions from clients.

    (CVE-2016-8615)

  - A flaw exists in cURL in the ConnectionExists() function     within file lib/url.c when checking credentials supplied     for reused connections due to the comparison being     case-insensitive. An unauthenticated, remote attacker     can exploit this to authenticate without knowing the     proper case of the username and password.
    (CVE-2016-8616)

  - An integer overflow condition exists in cURL in the     base64_encode() function within file lib/base64.c due to     improper validation of certain input.

  - A denial of service vulnerability exists in cURL in the     alloc_addbyter() function within file lib/mprintf.c due     to improper validation of overly long input when it is     supplied to the curl_maprintf() API method. An     unauthenticated, remote attacker can exploit this to     free already freed memory and thereby crash the program.
    (CVE-2016-8618)

  - 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)

    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.

Versions of cURL and libcurl prior to 7.51.0 are affected by multiple vulnerabilities :

 - A flaw exists in the International Domain Names (IDNA) handling when translating domain names to Punycode for DNS resolving. The issue is triggered as the outdated IDNA 2003 standard is used instead of IDNA 2008 for e.g. for the German 'LATIN SMALL LETTER SHARP S' Unicode character. This may result in incorrect translation for a domain name and in turn network traffic being directed to a different host than intended.
 - A flaw exists in the 'ConnectionExists()' function in 'lib/url.c' that is triggered when checking credentials supplied for reused connections, as the comparison is case-insensitive. This may allow a remote attacker to authenticate without knowing the proper case of the username and password.
 - An integer truncation flaw exists in the 'curl_easy_unescape()' function in 'lib/escape.c' that is triggered when handling overly large URLs. This may allow a context-dependent attacker to cause a heap-based buffer overflow, crashing a process linked against the library or potentially allowing the execution of arbitrary code.
 - An integer overflow condition exists in the 'base64_encode()' function in 'lib/base64.c' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to cause a heap-based buffer overflow, crashing a process linked against the library or potentially allowing the execution of arbitrary code.
 - A flaw exists in the 'alloc_addbyter()' function in 'lib/mprintf.c' that is triggered as overly long input is not properly validated when supplied to the 'curl_maprintf()' API method. This may allow a context-dependent attacker to free already freed memory and crash a process linked against the library.
 - A use-after-free error exists in 'lib/cookie.c' that is triggered when handling shared cookies. This may allow a context-dependent attacker to dereference already freed memory and potentially disclose memory contents.
 - A flaw exists in the 'parseurlandfillconn()' function in 'lib/url.c' that is triggered when parsing the authority component of an URL with the hostname part ending in a '#' character. This may allow a context-dependent attacker to establish a connection to a different host than intended.
 - A double-free error exists in the 'read_data()' function in 'lib/security.c' that is triggered when handling Kerberos authentication. This may allow a context-dependent attacker to free already freed memory and have an unspecified impact.
 - A flaw exists in the 'Curl_cookie_init()' function in 'lib/cookie.c' that is triggered when handling cookies. This may allow a context-dependent attacker to inject new cookies for arbitrary domains.
 - An out-of-bounds read flaw exists in the 'parsedate()' function in 'lib/parsedate.c' that is triggered when handling dates. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.
 - An out-of-bounds access flaw exists in 'tool_urlglob.c' within the globbing feature. This may allow a context-dependent attacker to potentially disclose memory contents or execute arbitrary code.
