5.0 MEDIUM — AV:N/AC:L/Au:N/C:N/I:P/A:N

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 configurations

• bzip bzip2 0.9.0 • bzip bzip2 0.9.0a • bzip bzip2 0.9.0b • bzip bzip2 0.9.0c • bzip bzip2 0.9.5a • bzip bzip2 0.9.5b • bzip bzip2 0.9.5c • bzip bzip2 0.9.5d • bzip bzip2 1.0 • bzip bzip2 1.0.1
