This update for libxml2 fixes the following issues: Security issues fixed :
CVE-2017-9050: heap-based buffer overflow (xmlDictAddString func) [bsc#1039069, bsc#1039661]
CVE-2017-9049: heap-based buffer overflow (xmlDictComputeFastKey func) [bsc#1039066]
CVE-2017-9048: stack overflow vulnerability (xmlSnprintfElementContent func) [bsc#1039063]
CVE-2017-9047: stack overflow vulnerability (xmlSnprintfElementContent func) [bsc#1039064] A clarification for the previously released update: For CVE-2016-9318 we decided not to ship a fix since it can break existing setups. Please take appropriate actions if you parse untrusted XML files and use the new
-noxxe flag if possible (bnc#1010675, bnc#1013930).
