CVE-2016-1838

TITLE

plural Apple Used in products libxml2 of xmlPArserPrintFileContextInternal Service disruption in functions (DoS) Vulnerabilities

DESCRIPTION

The xmlPArserPrintFileContextInternal function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document. Apple Mac OS X, watchOS, iOS, and tvOS are prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code and bypass security restrictions. Failed exploit attempts may result in a denial-of-service condition. Versions prior to iOS 9.3.2, watchOS 2.2.1, Mac OS X 10.11.5, and tvOS 9.2.1 are vulnerable. in the United States. Apple iOS is an operating system developed for mobile devices; watchOS is a smart watch operating system; OS X El Capitan is a dedicated operating system developed for Mac computers; tvOS is a smart TV operating system. It supports multiple encoding formats, XPath analysis, Well-formed and valid verification, etc. CVE-ID CVE-2016-1847 : Tongbo Luo and Bo Qu of Palo Alto Networks Installation note: Instructions on how to update your Apple Watch software are available at https://support.apple.com/en-us/HT204641 To check the version on your Apple Watch, open the Apple Watch app on your iPhone and select "My Watch > General > About". -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: libxml2 security update Advisory ID: RHSA-2016:1292-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2016:1292 Issue date: 2016-06-23 CVE Names: CVE-2016-1762 CVE-2016-1833 CVE-2016-1834 CVE-2016-1835 CVE-2016-1836 CVE-2016-1837 CVE-2016-1838 CVE-2016-1839 CVE-2016-1840 CVE-2016-3627 CVE-2016-3705 CVE-2016-4447 CVE-2016-4448 CVE-2016-4449 ===================================================================== 1.

Description: The libxml2 library is a development toolbox providing the implementation of various XML standards. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or execute arbitrary code with the permissions of the user running the application. (CVE-2016-1834, CVE-2016-1840) Multiple denial of service flaws were found in libxml2. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, could cause that application to crash. (CVE-2016-1762, CVE-2016-1833, CVE-2016-1835, CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, CVE-2016-1839, CVE-2016-3627, CVE-2016-3705, CVE-2016-4447, CVE-2016-4448, CVE-2016-4449) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 For the update to take effect, all applications linked to the libxml2 library must be restarted, or the system rebooted. 5.
