ClamAV: Multiple Denials of Service

ClamAV: Multiple Denials of Service Multiple vulnerabilities in ClamAV may result in a Denial of Service. clamav 2008-09-25 2008-09-25 236665 remote 0.94 0.94

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 (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:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.94"
