Synopsis

========

 

Multiple vulnerabilities in ClamAV may result in a Denial of Service.

 

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 < 0.94 >= 0.94

 

Description

===========

 

Hanno boeck reported an error in libclamav/chmunpack.c when processing

CHM files (CVE-2008-1389). Other unspecified vulnerabilites were also

reported, including a NULL pointer dereference in libclamav

(CVE-2008-3912), memory leaks in freshclam/manager.c (CVE-2008-3913),

and file descriptor leaks in libclamav/others.c and libclamav/sis.c

(CVE-2008-3914).

 

Impact

======

 

A remote attacker could entice a user or automated system to scan a

specially crafted CHM, possibly resulting in a Denial of Service

(daemon crash). The other attack vectors mentioned above could also

result in 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-0.94"
