Chris Evans discovered that a specially crafted archive can trigger an infinite loop in bzip2, a high-quality block-sorting file compressor.
During uncompression this results in an indefinitely growing output file which will finally fill up the disk. On systems that automatically decompress bzip2 archives this can cause a denial of service.
