Decompression bombs
A Decompression Bomb is a compressed-format file that expands to fill your disk. The bomber sends you an email with a compressed attachment designed to choke a virus scanner or the like. This article describes in more detail how different compression schemes can be exploited. For example, using GZIP to repeatedly compress a specific byte stream in three stages can result in a file of only 5928 bytes that when expanded is 100 gigabytes!. Other file formats that use compression are vulnerable as well, for example a GIF file that represents a 6000 x 6000 black rectangle compresses down to 25527 bytes but will expand to over 100 megabytes when represented as a 24-bit image.
