Descriptions

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.

bzip2 anteriores a 1.0.2 en FreeBSD 4.5 y anteriores, y otros Sistemas Operativos, no usan la etiqueta O_EXCL para crear ficheros durante la descomprensión y no alertan al usuario de que un fichero ya existente podría ser sobreescrito, lo cual podría permitir a atacantes remotos la sobreescritura de ficheros mediante un archivo bzip2.
