Synopsis
========
ClamAV is vulnerable to a buffer overflow which may lead to remote
execution of arbitrary code.
Background
==========
ClamAV is a GPL virus scanner.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-antivirus/clamav < 0.88 >= 0.88
Description
===========
Zero Day Initiative (ZDI) reported a heap buffer overflow
vulnerability. The vulnerability is due to an incorrect boundary check
of the user-supplied data prior to copying it to an insufficiently
sized memory buffer. The flaw occurs when the application attempts to
handle compressed UPX files.
Impact
======
For example by sending a maliciously crafted UPX file into a mail
server that is integrated with ClamAV, a remote attacker's supplied
code could be executed with escalated privileges.
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"
