An\nattacker could use this to specially construct XML data that\ncould cause a denial of service or possibly execute arbitrary\ncode. (CVE-2017-0663)\n\nIt was discovered that libxml2 did not properly validate parsed entity\nreferences. An attacker could use this to specially construct XML\ndata that could expose sensitive information. (CVE-2017-7375)\n\nIt was discovered that a buffer overflow existed in libxml2 when\nhandling HTTP redirects.
