An unauthenticated,     remote attacker can exploit this to dereference already     freed memory, potentially resulting in the execution of     arbitrary code. (CVE-2016-5421)

  - Multiple stored cross-site scripting (XSS)   	vulnerabilities exist due to improper validation of   	user-supplied input. An authenticated, remote attacker   	can exploit these, via a specially crafted request, to   	execute arbitrary script code in a user's browsers   	session. (CVE-2016-9261)

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 7.50.1 are affected by multiple vulnerabilities :

 - A flaw exists in 'lib/vtls/vtls.c' due to the program attempting to resume TLS sessions even if the client certificate fails. This may allow a context-dependent attacker to bypass validation mechanisms. (CVE-2016-5419)
 - A use-after-free error exists in the 'close_all_connections()' function in 'lib/multi.c'. The issue is triggered as connection pointers are not properly cleared for easy handles. This may allow a context-dependent attacker to dereference already freed memory and have an unspecified impact that may potentially include code execution. (CVE-2016-5421)

This update for curl fixes the following issues :

Security issues fixed :

  - CVE-2016-5419: TLS session resumption client cert bypass     (bsc#991389)

  - CVE-2016-5420: Re-using connections with wrong client     cert (bsc#991390)

  - CVE-2016-5421: use of connection struct after free     (bsc#991391)

  - CVE-2016-7141: Fixed incorrect reuse of client     certificates with NSS (bsc#997420)

Also the following bug was fixed :

  - fixing a performance issue (bsc#991746)

This update for curl fixes the following issues :

  - fixing a performance regression with FTP (boo#991746)

  - TLS session resumption client cert bypass (boo#991389,     CVE-2016-5419)

  - Re-using connections with wrong client cert (boo#991390,     CVE-2016-5420)

  - use of connection struct after free (boo#991391,     CVE-2016-5421)

curl and libcurl before 7.50.1 do not prevent TLS session resumption when the client certificate has changed, which allows remote attackers to bypass intended restrictions by resuming a session. (CVE-2016-5419)

curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.
(CVE-2016-5420)

libcurl before 7.50.1 allows attackers to control which connection is used or possibly have unspecified other impact via unknown vectors.
(CVE-2016-5421)

- fix re-using connections with wrong client cert     (CVE-2016-5420)

  - fix TLS session resumption client cert bypass     (CVE-2016-5419)

  - fix use of connection struct after free (CVE-2016-5421)

Bru Rom discovered that curl incorrectly handled client certificates when resuming a TLS session. (CVE-2016-5419)

It was discovered that curl incorrectly handled client certificates when reusing TLS connections. (CVE-2016-5420)

Marcelo Echeverria and Fernando Munoz discovered that curl incorrectly reused a connection struct, contrary to expectations. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2016-5421).

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

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.
