Antivirus Mail Scanners DoS

[Zhen-Xjell]

{QUOTE-> Most Antivirus applications uncompress archives before scanning them for viruses. A specially constructed compressed file containing only NULL values (or any other repeating one character value) will be a size of only a few bytes when compressed, but when uncompressed it will be a few megabytes of "information". This could cause a denial of service attack against the Antivirus scanning engine, by exhausting all available memory or disk space. <-QUOTE}
