"The version of the IrfanView MrSID plugin (MrSID.dll) installed on the
remote Windows host is a version prior to 4.37.  It is, therefore,
affected by multiple buffer overflow vulnerabilities :

  - A stack-based buffer overflow exists due to improper
    validation of the 'IMAGE' tag. (CVE-2013-3944)

  - A heap-based buffer overflow exists due to improper
    validation of the 'nband' tag. (CVE-2013-3945)

  - An integer overflow exists due to improper validation
    of the 'levels' header, which could lead to a heap-based
    buffer overflow. (CVE-2013-3946)

An attacker can exploit these issues by sending a specially crafted SID
file, which could result in a denial of service or arbitrary code
execution."
