"CVE-2015-5312 The xmlStringLenDecodeEntities function in parser.c in
libxml2 before 2.9.3 does not properly prevent entity expansion, which
allows context-dependent attackers to cause a denial of service (CPU
consumption) via crafted XML data, a different vulnerability than
CVE-2014-3660.

CVE-2015-7497 Heap-based buffer overflow in the xmlDictComputeFastQKey
function in dict.c in libxml2 before 2.9.3 allows context-dependent
attackers to cause a denial of service via unspecified vectors.

CVE-2015-7498 Heap-based buffer overflow in the xmlParseXmlDecl
function in parser.c in libxml2 before 2.9.3 allows context-dependent
attackers to cause a denial of service via unspecified vectors related
to extracting errors after an encoding conversion failure.

CVE-2015-7499 Heap-based buffer overflow in the xmlGROW function in
parser.c in libxml2 before 2.9.3 allows context-dependent attackers to
obtain sensitive process memory information via unspecified vectors.

CVE-2015-7500 The xmlParseMisc function in parser.c in libxml2 before
2.9.3 allows context-dependent attackers to cause a denial of service
(out-of-bounds heap read) via unspecified vectors related to incorrect
entities boundaries and start tags.

CVE-2015-7941 libxml2 2.9.2 does not properly stop parsing invalid
input, which allows context-dependent attackers to cause a denial of
service (out-of-bounds read and libxml2 crash) via crafted XML data to
the (1) xmlParseEntityDecl or (2) xmlParseConditionalSections function
in parser.c, as demonstrated by non-terminated entities.

CVE-2015-7942 The xmlParseConditionalSections function in parser.c in
libxml2 does not properly skip intermediary entities when it stops
parsing invalid input, which allows context-dependent attackers to
cause a denial of service (out-of-bounds read and crash) via crafted
XML data, a different vulnerability than CVE-2015-7941.

CVE-2015-8241 The xmlNextChar function in libxml2 2.9.2 does not
properly check the state, which allows context-dependent attackers to
cause a denial of service (heap-based buffer over-read and application
crash) or obtain sensitive information via crafted XML data.

CVE-2015-8242 The xmlSAX2TextNode function in SAX2.c in the push
interface in the HTML parser in libxml2 before 2.9.3 allows
context-dependent attackers to cause a denial of service (stack-based
buffer over-read and application crash) or obtain sensitive
information via crafted XML data.

CVE-2015-8317 The xmlParseXMLDecl function in parser.c in libxml2
before 2.9.3 allows context-dependent attackers to obtain sensitive
information via an (1) unterminated encoding value or (2) incomplete
XML declaration in XML data, which triggers an out-of-bounds heap
read."

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

The libxml2 library is a development toolbox providing the
implementation of various XML standards.

Several denial of service flaws were found in libxml2, a library
providing support for reading, modifying, and writing XML and HTML
files. A remote attacker could provide a specially crafted XML or HTML
file that, when processed by an application using libxml2, would cause
that application to use an excessive amount of CPU, leak potentially
sensitive information, or in certain cases crash the application.
