Synopsis
========
Multiple vulnerabilities in ClamAV may result in the remote execution
of arbitrary code.
Background
==========
Clam AntiVirus is a free anti-virus toolkit for UNIX, designed
especially for e-mail scanning on mail gateways.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-antivirus/clamav < 0.93 >= 0.93
Description
===========
Multiple vulnerabilities have been reported:
* Damian Put reported a heap-based buffer overflow when processing
PeSpin packed PE binaries (CVE-2008-0314).
* Alin Rad Pop of Secunia Research reported a buffer overflow in the
cli_scanpe() function when processing Upack PE binaries
(CVE-2008-1100).
* Hanno Boeck reported an infinite loop when processing ARJ archives
(CVE-2008-1387).
* Damian Put and Thomas Pollet reported a heap-based buffer overflow
when processing WWPack compressed PE binaries (CVE-2008-1833).
* A buffer over-read was discovered in the rfc2231() function when
producing a string that is not NULL terminated (CVE-2008-1836).
* An unspecified vulnerability leading to "memory problems" when
scanning RAR files was reported (CVE-2008-1837).
* Thierry Zoller reported that scanning of RAR files could be
circumvented (CVE-2008-1835).
Impact
======
A remote attacker could entice a user or automated system to scan a
specially crafted file, possibly leading to the execution of arbitrary
code with the privileges of the user running ClamAV (either a system
user or the "clamav" user if clamd is compromised), or a Denial of
Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ClamAV users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.93"
