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.

Affected products

Bzip2: 0.9.0, 0.9.0a, 0.9.0b, 0.9.0c, 0.9.5a, 0.9.5b (+4)
