Synopsis
=======
ClamAV contains multiple vulnerabilities that could lead to remote
execution of arbitrary code or cause an application crash.
Background
=========
ClamAV is a GPL virus scanner.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-antivirus/clamav < 0.88.1 >= 0.88.1
Description
==========
ClamAV contains format string vulnerabilities in the logging code
(CVE-2006-1615). Furthermore Damian Put discovered an integer overflow
in ClamAV's PE header parser (CVE-2006-1614) and David Luyer discovered
that ClamAV can be tricked into performing an invalid memory access
(CVE-2006-1630).
Impact
=====
By sending a malicious attachment to a mail server running ClamAV, a
remote attacker could cause a Denial of Service or the execution of
arbitrary code. Note that the overflow in the PE header parser is only
exploitable when the ArchiveMaxFileSize option is disabled.
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-0.88.1"
