CVE-2016-4658

TITLE

Multiple Apple product libxml2 Memory corruption vulnerability

DESCRIPTION

xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory corruption) via a crafted XML document. Apple iOS, tvOS,MacOS and watchOS are prone to multiple security vulnerabilities. Attackers can exploit these issues to bypass security restrictions, obtain sensitive information, execute arbitrary code, cause a denial-of-service condition, perform unauthorized actions and gain system privileges; this may aid in launching further attacks. Versions prior to iOS 10, watchOS 3, MacOS 10.12, and tvOS 10 are vulnerable. Apple iOS, OS X, tvOS, and watchOS are all products of the American company Apple (Apple). Apple iOS is an operating system developed for mobile devices; Apple OS X is a dedicated operating system developed for Mac computers; tvOS is a smart TV operating system; watchOS is a smart watch operating system. A memory corruption vulnerability exists in Libxml2 in several Apple products. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: libxml2 security update Advisory ID: RHSA-2021:3810-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:3810 Issue date: 2021-10-12 CVE Names: CVE-2016-4658 ===================================================================== 1.
