Description

Integer signedness error in the archive_write_zip_data function in archive_write_set_format_zip.c in libarchive 3.1.2 and earlier when running on 64-bit machines allows context-dependent attackers to cause a denial of service (crash) via unspecified vectors which triggers an improper conversion between unsigned and signed types leading to a buffer overflow.
