Description

bzip2 before 1.0.2 in FreeBSD 4.5 and earlier OpenLinux 3.1 and 3.1.1 and possibly other operating systems does not use the O_EXCL flag to create files during decompression and does not warn the user if an existing file would be overwritten which could allow attackers to overwrite files via a bzip2 archive.
