Clam AntiVirus is vulnerable to integer overflows when handling several
file formats, potentially resulting in the execution of arbitrary code.

with mail servers to perform attachment scanning. Clam AntiVirus also
provides a command line scanner and a tool for fetching updates of the
virus database.

Description
==========
Neel Mehta and Alex Wheeler discovered that Clam AntiVirus is
vulnerable to integer overflows when handling the TNEF, CHM and FSG
