CVE-2019-11463
A memory leak in archive_read_format_zip_cleanup in archive_read_support_format_zip.c in libarchive 3.3.4-dev allows remote attackers to cause a denial of service via a crafted ZIP file because of a HAVE_LZMA_H typo.
Does this matter?
Lower severity and a low EPSS score (1.30%). Track it; it rarely justifies an emergency change on its own.
