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.

Weakness

The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
