CVE-2016-4300
Fixed in a distro release EPSS 5%
Integer overflow in the read_SubStreamsInfo function in archive_read_support_format_7zip.c in libarchive before 3.2.1 allows remote attackers to execute arbitrary code via a 7zip file with a large number of substreams, which triggers a heap-based buffer overflow.
