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.
A use-after-free flaw was found in the Xpointer implementation of libxml2. An attacker could use this flaw against an application parsing untrusted XML files and compiled with libxml2 to leak small amount of memory data.
