Description Andrej Nemec 2017-09-22 09:53:08 UTC 
libarchive 3.3.2 suffers from an out-of-bounds read within lha_read_data_none() in archive_read_support_format_lha.c when extracting a specially crafted lha archive, related to lha_crc16. An attacker could use this flaw to cause a denial of service.
