CVE-2017-18258 libxml2: Unrestricted memory usage in xz_head() function in xzlib.c
A flaw was found in libxml2 before 2.9.6. The xz_head function in xzlib.c in allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file.
