What an attacker can do

The source says libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035 and CVE-2018-9251. NVD’s CVSS 3.0 assessment (base score 6.5/10) rates confidentiality and integrity impact as none; availability impact as high.
