Input validation error in libarchive - CVE-2013-0211

Vulnerability details

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

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.
