Secunia Research has discovered a vulnerability in libarchive, which can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to an error in the "lha_read_file_header_1()" function (archive_read_support_format_lha.c), which can be exploited to trigger an out-of-bounds read memory access via a specially crafted archive. The vulnerability is confirmed in version 3.2.2. Other versions may also be affected.
