Clam AntiVirus is a free anti-virus toolkit for UNIX, designed
especially for e-mail scanning on mail gateways.
Hanno boeck reported an error in libclamav/chmunpack.c when processing
CHM files (CVE-2008-1389). Other unspecified vulnerabilities were also
reported, including a NULL pointer dereference in libclamav
(CVE-2008-3912), memory leaks in freshclam/manager.c (CVE-2008-3913),
and file descriptor leaks in libclamav/others.c and libclamav/sis.c
<impact type="normal">
A remote attacker could entice a user or automated system to scan a
specially crafted CHM, possibly resulting in a Denial of Service
(daemon crash). The other attack vectors mentioned above could also
result in a Denial of Service.
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-0.94&quot;</code>
