Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple vulnerabilities in ClamAV may result in a Denial of Service.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Clam AntiVirus is a free anti-virus toolkit for UNIX, designed
especially for e-mail scanning on mail gateways.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Hanno boeck reported an error in libclamav/chmunpack.c when processing
CHM files (CVE-2008-1389). Other unspecified vulnerabilites 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
(CVE-2008-3914).
Impact
=3D=3D=3D=3D=3D=3D
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.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All ClamAV users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dapp-antivirus/clamav-0.94"
