which can be exploited by malware to bypass certain scanning

SA17126

The weakness affects version 4.0.1.14 when scanning emails containing
malformed ".zip", ".rar" and ".arj" archives. Other versions may also
be affected.

NOTE: This is not an issue on client systems, as the malware is still
detected upon execution by the desktop on-access scanner.

SOLUTION:
Desktop on-access scanner should be used to ensure that the malware
is detected upon extraction.

Filter all compressed file archives at border gateways if they are
not required.
