When asking to get a file from a file:// URL, libcurl provides a feature that outputs meta-data about the file using HTTP-like headers. The code doing this would send the wrong buffer to the user (stdout or the application's provide callback), which could lead to other private data from the heap to get inadvertently displayed. The wrong buffer was an uninitialized memory area allocated on the heap and if it turned out to not contain any zero byte, it would continue and display the data following that buffer in memory.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - When asking to get a file from a file:// URL, libcurl provides a feature that outputs meta-data about the
    file using HTTP-like headers. The code doing this would send the wrong buffer to the user (stdout or the
    application's provide callback), which could lead to other private data from the heap to get inadvertently
    displayed. The wrong buffer was an uninitialized memory area allocated on the heap and if it turned out to
    not contain any zero byte, it would continue and display the data following that buffer in memory.
    (CVE-2017-1000099)

  - When doing a TFTP transfer and curl/libcurl is given a URL that contains a very long file name (longer
    than about 515 bytes), the file name is truncated to fit within the buffer boundaries, but the buffer size
    is still wrongly updated to use the untruncated length. This too large value is then used in the sendto()
    call, making curl attempt to send more data than what is actually put into the buffer. The endto()
    function will then read beyond the end of the heap based buffer. A malicious HTTP(S) server could redirect
    a vulnerable libcurl-using client to a crafted TFTP URL (if the client hasn't restricted which protocols
    it allows redirects to) and trick it to send private memory contents to a remote server over UDP. Limit
    curl's redirect protocols with --proto-redir and libcurl's with CURLOPT_REDIR_PROTOCOLS.
    (CVE-2017-1000100)

  - curl supports "globbing" of URLs, in which a user can pass a numerical range to have the tool iterate over
    those numbers to do a sequence of transfers. In the globbing function that parses the numerical range,
    there was an omission that made curl read a byte beyond the end of the URL if given a carefully crafted,
    or just wrongly written, URL. The URL is stored in a heap based buffer, so it could then be made to
    wrongly read something else instead of crashing. An example of a URL that triggers the flaw would be
    `http://ur%20[0-60000000000000000000`. (CVE-2017-1000101)

The remote NewStart CGSL host, running version MAIN 6.02, has curl packages installed that are affected by multiple vulnerabilities:

  - The redirect implementation in curl and libcurl 5.11 through 7.19.3, when CURLOPT_FOLLOWLOCATION is     enabled, accepts arbitrary Location values, which might allow remote HTTP servers to (1) trigger arbitrary     requests to intranet servers, (2) read or overwrite arbitrary files via a redirect to a file: URL, or (3)     execute arbitrary commands via a redirect to an scp: URL. (CVE-2009-0037)

  - The Curl_input_negotiate function in http_negotiate.c in libcurl 7.10.6 through 7.21.6, as used in curl     and other products, always performs credential delegation during GSSAPI authentication, which allows     remote servers to impersonate clients via GSSAPI requests. (CVE-2011-2192)

  - curl and libcurl 7.2x before 7.24.0 do not properly consider special characters during extraction of a     pathname from a URL, which allows remote attackers to conduct data-injection attacks via a crafted URL, as     demonstrated by a CRLF injection attack on the (1) IMAP, (2) POP3, or (3) SMTP protocol. (CVE-2012-0036)

  - Stack-based buffer overflow in the Curl_sasl_create_digest_md5_message function in lib/curl_sasl.c in curl     and libcurl 7.26.0 through 7.28.1, when negotiating SASL DIGEST-MD5 authentication, allows remote     attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in     the realm parameter in a (1) POP3, (2) SMTP or (3) IMAP message. (CVE-2013-0249)

  - 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)

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

An update of the curl package has been released.
