curl before version 7.51.0 uses outdated IDNA 2003 standard to handle International Domain Names and this may lead users to potentially and unknowingly issue network transfer requests to the wrong host.

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 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.

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

  - curl before version 7.51.0 uses outdated IDNA 2003 standard to handle International Domain Names and this     may lead users to potentially and unknowingly issue network transfer requests to the wrong host.
    (CVE-2016-8625)

  - curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used     option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for     sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer     to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-     text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing     the string provided by the application.

  - 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.

The remote host is affected by the vulnerability described in GLSA-201701-47 (cURL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in cURL. Please review the       CVE identifiers and bug reports referenced for details.
  Impact :

    Remote attackers could conduct a Man-in-the-Middle attack to obtain       sensitive information, cause a Denial of Service condition, or execute       arbitrary code.
  Workaround :

    There is no known workaround at this time.

The remote host is running a version of macOS that is 10.12.x prior to 10.12.2. It is, therefore, affected by multiple vulnerabilities in the following components :

  - apache_mod_php
  - AppleGraphicsPowerManagement
  - Assets
  - Audio
  - Bluetooth
  - CoreCapture
  - CoreFoundation
  - CoreGraphics
  - CoreMedia External Displays
  - CoreMedia Playback
  - CoreStorage
  - CoreText
  - curl
  - Directory Services
  - Disk Images
  - FontParser
  - Foundation
  - Grapher
  - ICU
  - ImageIO
  - Intel Graphics Driver
  - IOFireWireFamily
  - IOAcceleratorFamily
  - IOHIDFamily
  - IOKit
  - IOSurface
  - Kernel
  - kext tools
  - libarchive
  - LibreSSL
  - OpenLDAP
  - OpenPAM
  - OpenSSL
  - Power Management
  - Security
  - syslog
  - WiFi
  - xar

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

Furthermore, CVE-2016-6304, CVE-2016-7596, and CVE-2016-7604 also affect Mac OS X versions 10.10.5 and 10.11.6. However, this plugin does not check those versions.

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.

New curl packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, 14.2, and -current to fix security issues.
