File Overwrite Vulnerability in bzip2

CVE-2002-0759 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:P/A:N

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.
