"The remote Solaris system is missing necessary patches to address
security updates :

  - The tailMatch function in cookie.c in cURL and libcurl
    before 7.30.0 does not properly match the path domain
    when sending cookies, which allows remote attackers to
    steal cookies via a matching suffix in the domain of a
    URL. (CVE-2013-1944)

  - Heap-based buffer overflow in the curl_easy_unescape
    function in lib/escape.c in cURL and libcurl 7.7 through
    7.30.0 allows remote attackers to cause a denial of
    service (application crash) or possibly execute
    arbitrary code via a crafted string ending in a '%'
    (percent) character. (CVE-2013-2174)

  - cURL and libcurl 7.18.0 through 7.32.0, when built with
    OpenSSL, disables the certificate CN and SAN name field
    verification (CURLOPT_SSL_VERIFYHOST) when the digital
    signature verification (CURLOPT_SSL_VERIFYPEER) is
    disabled, which allows man-in-the-middle attackers to
    spoof SSL servers via an arbitrary valid certificate.
    (CVE-2013-4545)

  - cURL and libcurl 7.10.6 through 7.34.0, when more than
    one authentication method is enabled, re-uses NTLM
    connections, which might allow context-dependent
    attackers to authenticate as other users via a request.
    (CVE-2014-0015)"
