The 'globbing' feature in curl before version 7.51.0 has a flaw that leads to integer overflow and out-of-bounds read via user controlled input.

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.

  - 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.

CVE-2016-8623 : Use-after-free via shared cookies

CVE-2016-8624 : Invalid URL parsing with '#'

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

  - CVE-2016-8615     It was discovered that a malicious HTTP server could     inject new cookies for arbitrary domains into a cookie     jar.

  - CVE-2016-8616     It was discovered that when re-using a connection, curl     was doing case insensitive comparisons of user name and     password with the existing connections.

  - CVE-2016-8617     It was discovered that on systems with 32-bit addresses     in userspace (e.g. x86, ARM, x32), the output buffer     size value calculated in the base64 encode function     would wrap around if input size was at least 1GB of     data, causing an undersized output buffer to be     allocated.

  - CVE-2016-8618     It was discovered that the curl_maprintf() function     could be tricked into doing a double-free due to an     unsafe size_t multiplication on systems using 32 bit     size_t variables.

  - CVE-2016-8619     It was discovered that the Kerberos implementation could     be tricked into doing a double-free when reading one of     the length fields from a socket.

  - CVE-2016-8620     It was discovered that the curl tool's 'globbing'     feature could write to invalid memory areas when parsing     invalid ranges.

  - CVE-2016-8621     It was discovered that the function curl_getdate could     read out of bounds when parsing invalid date strings.

  - CVE-2016-8622     It was discovered that the URL percent-encoding decode     function would return a signed 32bit integer variable as     length, even though it allocated a destination buffer     larger than 2GB, which would lead to a out-of-bounds     write.

  - CVE-2016-8623     It was discovered that libcurl could access an     already-freed memory area due to concurrent access to     shared cookies. This could lead to a denial of service     or disclosure of sensitive information.

  - CVE-2016-8624     It was discovered that curl wouldn't parse the authority     component of a URL correctly when the host name part     ends with a '#' character, and could be tricked into     connecting to a different host.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3123-1 advisory.

    It was discovered that curl incorrectly reused client certificates when built with NSS. A remote attacker     could possibly use this issue to hijack the authentication of a TLS connection. (CVE-2016-7141)

    Nguyen Vu Hoang discovered that curl incorrectly handled escaping certain strings. A remote attacker could     possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2016-7167)

    It was discovered that curl incorrectly handled storing cookies. A remote attacker could possibly use this     issue to inject cookies for arbitrary domains in the cookie jar. (CVE-2016-8615)

    It was discovered that curl incorrect handled case when comparing user names and passwords. A remote     attacker with knowledge of a case-insensitive version of the correct password could possibly use this     issue to cause a connection to be reused. (CVE-2016-8616)

    It was discovered that curl incorrect handled memory when encoding to base64. A remote attacker could     possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2016-8617)

    It was discovered that curl incorrect handled memory when preparing formatted output. A remote attacker     could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly     execute arbitrary code. (CVE-2016-8618)

    It was discovered that curl incorrect handled memory when performing Kerberos authentication. A remote     attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or     possibly execute arbitrary code. (CVE-2016-8619)

    Lut Nguyn discovered that curl incorrectly handled parsing globs. A remote attacker could possibly     use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary     code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-8620)

    Lut Nguyn discovered that curl incorrectly handled converting dates. A remote attacker could     possibly use this issue to cause curl to crash, resulting in a denial of service. (CVE-2016-8621)

    It was discovered that curl incorrectly handled URL percent-encoding decoding. A remote attacker could     possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2016-8622)

    It was discovered that curl incorrectly handled shared cookies. A remote server could possibly obtain     incorrect cookies or other sensitive information. (CVE-2016-8623)

    Fernando Muoz discovered that curl incorrect parsed certain URLs. A remote attacker could possibly use     this issue to trick curl into connecting to a different host. (CVE-2016-8624)
