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"
