curl before version 7.52.0 is vulnerable to a buffer overflow when doing a large floating point output in libcurl's implementation of the printf() functions. If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks.

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.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - curl: NTLM password overflow via integer overflow (CVE-2018-14618)

  - 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)

  - The default configuration in cURL and libcurl 7.10.6 before 7.36.0 re-uses (1) SCP, (2) SFTP, (3) POP3,     (4) POP3S, (5) IMAP, (6) IMAPS, (7) SMTP, (8) SMTPS, (9) LDAP, and (10) LDAPS connections, which might     allow context-dependent attackers to connect as other users via a request, a similar issue to     CVE-2014-0015. (CVE-2014-0138)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

  - curl: NTLM password overflow via integer overflow (CVE-2018-14618)

  - The default configuration for cURL and libcurl before 7.42.1 sends custom HTTP headers to both the proxy     and destination server, which might allow remote proxy servers to obtain sensitive information by reading     the header contents. (CVE-2015-3153)

  - The ConnectionExists function in lib/url.c in libcurl before 7.47.0 does not properly re-use NTLM-     authenticated proxy connections, which might allow remote attackers to authenticate as other users via a     request, a similar issue to CVE-2014-0015. (CVE-2016-0755)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - curl: FTP wildcard out of bounds read (CVE-2017-8817)

  - CRLF injection vulnerability in libcurl 6.0 through 7.x before 7.40.0, when using an HTTP proxy, allows     remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via CRLF     sequences in a URL. (CVE-2014-8150)

  - The default configuration for cURL and libcurl before 7.42.1 sends custom HTTP headers to both the proxy     and destination server, which might allow remote proxy servers to obtain sensitive information by reading     the header contents. (CVE-2015-3153)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Several vulnerabilities were discovered in cURL, an URL transfer library.

CVE-2016-7141

When built with NSS and the libnsspem.so library is available at runtime, allows an remote attacker to hijack the authentication of a TLS connection by leveraging reuse of a previously loaded client certificate from file for a connection for which no certificate has been set, a different vulnerability than CVE-2016-5420.

CVE-2016-7167

Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.

CVE-2016-9586

Curl is vulnerable to a buffer overflow when doing a large floating point output in libcurl's implementation of the printf() functions. If there are any applications that accept a format string from the outside without necessary input filtering, it could allow remote attacks.

CVE-2018-16839

Curl is vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service.

CVE-2018-16842

Curl is vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 7.38.0-4+deb8u13.

According to the versions of the curl package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - It was found that libcurl did not safely parse FTP URLs     when using the CURLOPT_FTP_FILEMETHOD method. An     attacker, able to provide a specially crafted FTP URL     to an application using libcurl, could write a NULL     byte at an arbitrary location, resulting in a crash, or     an unspecified behavior.(CVE-2018-1000120)

  - A NULL pointer dereference flaw was found in the way     libcurl checks values returned by the openldap     ldap_get_attribute_ber() function. A malicious LDAP     server could use this flaw to crash a libcurl client     application via a specially crafted LDAP     reply.(CVE-2018-1000121)

  - A buffer over-read exists in curl 7.20.0 to and     including curl 7.58.0 in the RTSP+RTP handling code     that allows an attacker to cause a denial of service or     information leakage(CVE-2018-1000122)

  - curl version curl 7.20.0 to and including curl 7.59.0     contains a Buffer Over-read vulnerability in denial of     service that can result in curl can be tricked into     reading data beyond the end of a heap based buffer used     to store downloaded rtsp content.(CVE-2018-1000301)

  - curl version curl 7.20.0 to and including curl 7.59.0     contains a Buffer Over-read vulnerability in denial of     service that can result in curl can be tricked into     reading data beyond the end of a heap based buffer used     to store downloaded rtsp content.(CVE-2016-9586)

  - libcurl may read outside of a heap allocated buffer     when doing FTP. When libcurl connects to an FTP server     and successfully logs in (anonymous or not), it asks     the server for the current directory with the `PWD`     command. The server then responds with a 257 response     containing the path, inside double quotes. The returned     path name is then kept by libcurl for subsequent uses.
    Due to a flaw in the string parser for this directory     name, a directory name passed like this but without a     closing double quote would lead to libcurl not adding a     trailing NUL byte to the buffer holding the name. When     libcurl would then later access the string, it could     read beyond the allocated heap buffer and crash or     wrongly access data beyond the buffer, thinking it was     part of the path. A malicious server could abuse this     fact and effectively prevent libcurl-based clients to     work with it - the PWD command is always issued on new     FTP connections and the mistake has a high chance of     causing a segfault. The simple fact that this has issue     remained undiscovered for this long could suggest that     malformed PWD responses are rare in benign servers. We     are not aware of any exploit of this flaw. This bug was     introduced in commit     [415d2e7cb7](https://github.com/curl/curl/commit/415d2e     7cb7), March 2005. In libcurl version 7.56.0, the     parser always zero terminates the string but also     rejects it if not terminated properly with a final     double quote.i1/4^CVE-2017-1000254i1/4%0

  - The FTP wildcard function in curl and libcurl before     7.57.0 allows remote attackers to cause a denial of     service (out-of-bounds read and application crash) or     possibly have unspecified other impact via a string     that ends with an '[' character.The FTP wildcard     function in curl and libcurl before 7.57.0 allows     remote attackers to cause a denial of service     (out-of-bounds read and application crash) or possibly     have unspecified other impact via a string that ends     with an '[' character.i1/4^CVE-2017-8817i1/4%0

The remote host is running a version of Mac OS X version 10.x prior to 10.12.6, and is affected by multiple vulnerabilities :

 - An overflow condition exists in the curl component in the 'dprintf_formatf()' function that is triggered when handling floating point conversion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9586)
 - A flaw exits in the curl component in the 'randit()' function within file lib/rand.c due to improper initialization of the 32-bit random value, which is used, for example, to generate Digest and NTLM authentication nonces, resulting in weaker cryptographic operations than expected. (CVE-2016-9594)
 - A flaw exists in the curl component in the 'allocate_conn()' function in lib/url.c when using the OCSP stapling feature for checking a X.509 certificate revocation status. The issue is triggered as the request option for OCSP stapling is not properly passed to the TLS library, resulting in no error being returned even when no proof of the validity of the certificate could be provided. A man-in-the-middle attacker can exploit this to provide a revoked certificate. (CVE-2017-2629)
 - A remote code execution vulnerability exists in the CoreAudio component due to improper validation of user-supplied input when handling movie files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted movie file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7008)
 - A memory corruption issue exists in the IOUSBFamily component due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7009)
 - Multiple out-of-bounds read errors exist in the libxml2 component due to improper handling of specially crafted XML documents. An unauthenticated, remote attacker can exploit these to disclose user information. (CVE-2017-7010, CVE-2017-7013)
 - Multiple memory corruption issues exist in the Intel Graphics Driver component due to improper validation of input. A local attacker can exploit these issues to execute arbitrary code with elevated privileges. (CVE-2017-7014, CVE-2017-7017, CVE-2017-7035, CVE-2017-7044)
 - A remote code execution vulnerability exists in the Audio component due to improper validation of user-supplied input when handling audio files.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that libcurl's implementation of the printf() functions triggers a buffer overflow when doing a large floating point output. The bug occurs when the conversion outputs more than 255 bytes.

The flaw happens because the floating point conversion is using system functions without the correct boundary checks.

If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks.

This flaw does not exist in the command line tool.

For Debian 7 'Wheezy', these problems have been fixed in version 7.26.0-1+wheezy18.

We recommend that you upgrade your curl packages.
