CVE-2016-1841

TITLE

plural Apple Used in products libxslt Vulnerable to arbitrary code execution

DESCRIPTION

libxslt, 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 execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site. 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. libxslt is an XSLT (XML language for defining XML transformations) C library developed for the GNOME project. This was addressed by enabling HTTPS for shared links. 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". ========================================================================== Ubuntu Security Notice USN-3271-1 April 28, 2017 libxslt vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.04 - Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in Libxslt. Software Description: - libxslt: XSLT processing library Details: Holger Fuhrmannek discovered an integer overflow in the xsltAddTextString() function in Libxslt. (CVE-2017-5029) Nicolas Gregoire discovered that Libxslt mishandled namespace nodes. An attacker could use this to craft a malicious document that, when opened, could cause a denial of service (application crash) or possibly execute arbtrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-1683) Sebastian Apelt discovered that a use-after-error existed in the xsltDocumentFunctionLoadDocument() function in Libxslt. This issue only affected Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-1841) It was discovered that a type confusion error existed in the xsltStylePreCompute() function in Libxslt. An attacker could use this to craft a malicious XML file that, when opened, caused a denial of service (application crash). This issue only affected Ubuntu 14.04 LTS and Ubuntu 12.04 LTS. (CVE-2015-7995) Nicolas Gregoire discovered the Libxslt mishandled the 'i' and 'a' format tokens for xsl:number data. An attacker could use this to craft a malicious document that, when opened, could cause a denial of service (application crash). This issue only affected Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-1684) It was discovered that the xsltFormatNumberConversion() function in Libxslt did not properly handle empty decimal separators. An attacker could use this to craft a malicious document that, when opened, could cause a denial of service (application crash). This issue only affected Ubuntu 16.10, Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-4738) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.04: libxslt1.1 1.1.29-2ubuntu0.1 Ubuntu 16.10: libxslt1.1 1.1.29-1ubuntu0.1 Ubuntu 16.04 LTS: libxslt1.1 1.1.28-2.1ubuntu0.1 Ubuntu 14.04 LTS: libxslt1.1 1.1.28-2ubuntu0.1 Ubuntu 12.04 LTS: libxslt1.1 1.1.26-8ubuntu1.4 In general, a standard system update will make all the necessary changes.
