This update for libxml2 fixes several issues. Theses security issues were fixed :
CVE-2017-16932: Fixed infinite recursion could lead to an infinite loop or memory exhaustion when expanding a parameter entity in a DTD (bsc#1069689).
CVE-2017-15412: Prevent use after free when calling XPath extension functions that allowed remote attackers to cause DoS or potentially RCE (bsc#1077993)
CVE-2016-5131: Use-after-free vulnerability in libxml2 allowed remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function. (bsc#1078813)
CVE-2017-5130: Fixed a potential remote buffer overflow in function xmlMemoryStrdup() (bsc#1078806)
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
