Multiple vulnerabilities in ClamAV may result in a Denial of Service.
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 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).
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:
