Date: October 24, 2006
Bugs: #151561
ID: 200610-10

Synopsis
========
ClamAV is vulnerable to a heap-based buffer overflow potentially
allowing remote execution of arbitrary code and a Denial of Service.
Background
==========
ClamAV is a GPL virus scanner.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-antivirus/clamav < 0.88.5 >= 0.88.5
Description
===========
Damian Put and an anonymous researcher reported a potential heap-based
buffer overflow vulnerability in rebuildpe.c responsible for the
rebuilding of an unpacked PE file, and a possible crash in chmunpack.c
in the CHM unpacker.
Impact
======
By sending a malicious attachment to a mail server running ClamAV, or
providing a malicious file to ClamAV through any other method, a remote
attacker could cause a Denial of Service and potentially the execution
of arbitrary code with the permissions of the user running ClamAV.
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-0.88.5"
