CVE-2017-5601
An error in the lha_read_file_header_1() function (archive_read_support_format_lha.c) in libarchive 3.2.2 allows remote attackers to trigger an out-of-bounds read memory access and subsequently cause a crash via a specially crafted archive.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.50%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
