According to its version, the ClamAV clamd antivirus daemon on the remote host is earlier than 0.97.5 and is, therefore, potentially affected by the following vulnerabilities :
Errors exist related to the ‘TAR’ file parser that can allow malware detection to be bypassed when handling such files containing a length field having certain values. (CVE-2012-1457, CVE-2012-1459)
An error exists related to the ‘CHM’ file parser that can allow malware detection to be bypassed when handling such files containing a crafted reset interval in the ‘LZXC’ header. (CVE-2012-1458)
