remote execution of arbitrary code.

ClamAV is a GPL virus scanner.
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 type="high">
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.
There is no known workaround at this time.
All ClamAV users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-antivirus/clamav-0.90.2&quot;</code>
