Details

It was discovered that a type confusion error existed in libxml2. An
attacker could use this to specially construct XML data that
could cause a denial of service or possibly execute arbitrary
code. (CVE-2017-0663)

It was discovered that libxml2 did not properly validate parsed entity
references. An attacker could use this to specially construct XML
data that could expose sensitive information. (CVE-2017-7375)

It was discovered that a buffer overflow existed in libxml2 when
handling HTTP redirects. An attacker could use this to specially
construct XML data that could cause a denial of service or possibly
execute arbitrary code. (CVE-2017-7376)

Marcel Böhme and Van-Thuan Pham discovered a buffer overflow in
libxml2 when handling elements. An attacker could use this to specially
construct XML data that could cause a denial of service or possibly
execute arbitrary code. (CVE-2017-9047)

Marcel Böhme and Van-Thuan Pham discovered a buffer overread
in libxml2 when handling elements. An attacker could use this
to specially construct XML data that could cause a denial of
service. (CVE-2017-9048)

Marcel Böhme and Van-Thuan Pham discovered multiple buffer overreads
in libxml2 when handling parameter-entity references. An attacker
could use these to specially construct XML data that could cause a
denial of service. (CVE-2017-9049, CVE-2017-9050)
