Synopsis
========
Clam AntiVirus is vulnerable to integer overflows when handling several
file formats, potentially resulting in the execution of arbitrary code.
Background
==========
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.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-antivirus/clamav < 0.86.2 >= 0.86.2
Description
===========
Neel Mehta and Alex Wheeler discovered that Clam AntiVirus is
vulnerable to integer overflows when handling the TNEF, CHM and FSG
file formats.
Impact
======
By sending a specially-crafted file an attacker could execute arbitrary
code with the permissions of the user running Clam AntiVirus.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Clam AntiVirus users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.86.2"
