Synopsis
=======
Multiple vulnerabilities have been discovered in ClamAV allowing for
the remote execution of arbitrary code.
Background
=========
ClamAV is a GPL virus scanner.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-antivirus/clamav < 0.90.2 >= 0.90.2
Description
==========
iDefense Labs have reported a stack-based buffer overflow in the
cab_unstore() function when processing negative values in .cab files.
Multiple file descriptor leaks have also been reported in chmunpack.c,
pdf.c and dblock.c when processing .chm files.
Impact
=====
A remote attacker could send a specially crafted CHM file to the
scanner, possibly resulting in the remote execution of arbitrary code
with the privileges 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-0.90.2"
