Description Arvid Requate

2016-11-08 19:17:39 CET

Upstream Debian package version 2.8.0+dfsg1-7+wheezy7 fixes this issue:

* libxml2 in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document. (CVE-2016-4658)

Also:

* legacy xmlXPtrRangeToFunction could be abused to trigger use-after-free error with the potential for remote code execution (CVE-2016-5131)
