Date : 2016-11-01
CVE-ID : CVE-2016-4658 CVE-2016-5131
Package : libxml2
Type : arbitrary code execution
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package libxml2 before version 2.9.4+12+ge905f08-1 is vulnerable to
arbitrary code execution.
Upgrade to 2.9.4+12+ge905f08-1.
The problems have been fixed upstream but no release is available yet.
None.
A use-after-free vulnerability via namespace nodes in XPointer ranges
was found in libxml2.
Bugs in xmlXPathEvalExpr and xmlXPtrRangeToFunction can lead to a use-
after-free and allow control of the instruction pointer.
A remote attacker is able to use a specially crafted XPath payload to
execute arbitrary code.
