CVE-2017-18258

Priority
Description
The xz_head function in xzlib.c in libxml2 before 2.9.6 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.
