Clam AntiVirus is a GPL anti-virus toolkit, designed for integration
|
|
|
|
|
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.

|
|
|
|
vulnerable to integer overflows when handling the TNEF, CHM and FSG
|
|
|
|
|
file formats.

<impact type="high">
|
|
|
|
|
<p>
|
|
|
|
|
By sending a specially-crafted file an attacker could execute arbitrary
|
|
|
|
|
code with the permissions of the user running Clam AntiVirus.
