Moreover, If you download such archives from an internet location, or copy/paste such files from a destination. Those Vulnerable "Antivirus Software?s" with their auto-protect engines active, may also trigger a DoS. An attacker can create a big file, dd if=/dev/zero of=/crash bs=9999 and compress the file. [Well there are ways to squeeze a terabyte of such data to few kilobytes] An attacker could construct such archive and if send to a vulnerable AV gateway, multiple of times may result in system un-stability, high CPU use for long time, system hang/crash etc... Note: This is just a simple proof of concept, smaller archive >10kb can be created that contain a terabyte of data... Moreover it's not safe to set automatically 'Quarantine/delete' option set for your AV scanner as it may try to Quarantine the virus by extracting the archive.
