Vulnerability Insight:
Updated libxml2 packages fix security vulnerabilities:
In libxml2 before 2.9.3, one case where when dealing with entities expansion,
it failed to exit, leading to a denial of service (CVE-2015-5312).
In libxml2 before 2.9.3, it was possible to hit a negative offset in the name
indexing used to randomize the dictionary key generation, causing a heap
buffer overflow in xmlDictComputeFastQKey (CVE-2015-7497).
In libxml2 before 2.9.3, after encoding conversion failures, the parser was
continuing to process to extract more errors, which can potentially lead to
unexpected behaviour (CVE-2015-7498).
In libxml2 before 2.9.3, the parser failed to detect a case where the current
pointer to the input was out of range, leaving it in an incoherent state
(CVE-2015-7499).
In libxml2 before 2.9.3, a memory access error could happen while processing
a start tag due to incorrect entities boundaries (CVE-2015-7500).

mode (CVE-2015-8242).
In libxml2 before 2.9.3, out of bounds heap reads could happen due to failure
