"According to its version, the ClamAV clamd antivirus daemon on the
remote host is prior to 0.98.6. It is, therefore, affected by the
following vulnerabilities :

  - An out-of-bounds access flaw exists in the unupack()
    function that is triggered when parsing a specially
    crafted Upack packer file. A remote attacker can exploit
    this to crash the application, resulting in a denial of
    service condition. (CVE-2014-9328)

  - An out-of-bounds access flaw exists that is triggered
    when parsing maliciously crafted Yoda Crypter and MEW
    packer files. A remote attacker can exploit this to
    crash the application, resulting in a denial of service
    condition. (CVE-2015-1461)
 
  - An out-of-bounds access flaw exists that is triggered
    when parsing a specially crafted UPX packer file. A
    remote attacker can exploit this to crash the
    application, resulting in a denial of service condition.
    (CVE-2015-1462)

  - A signedness flaw exists in the petite_inflate2x_1to9()
    function in 'libclamav/petite.c' that allows a remote
    attacker with a specially crafted petite packer file
    to cause a denial of service. (CVE-2015-1463)

  - An integer overflow condition exists in upx.c due to
    improper validation of user-supplied input when scanning
    EXE files. An attacker can exploit this to cause a
    heap-based buffer overflow, resulting in a denial of
    service condition or the execution of arbitrary code.");
