(POV-Ray: User-assisted execution of arbitrary code)

    POV-Ray uses a statically linked copy of libpng to view and output PNG
    files. The version shipped with POV-Ray is vulnerable to CVE-2008-3964,
    CVE-2008-1382, CVE-2006-3334, CVE-2006-0481, CVE-2004-0768. A bug in
    POV-Ray's build system caused it to load the old version when your
    installed copy of libpng was >=media-libs/libpng-1.2.10.
  
Impact :

    An attacker could entice a user to load a specially crafted PNG file as
    a texture, resulting in the execution of arbitrary code with the
    permissions of the user running the application.
  
Workaround :

    There is no known workaround at this time."

  - CAN-2004-0597
    Multiple buffer overflows exist, including when handling
    transparency chunk data, which could be exploited to
    cause arbitrary code to be executed when a specially
    crafted PNG image is processed

  - CAN-2004-0598

    Multiple NULL pointer dereferences in png_handle_iCPP()
    and elsewhere could be exploited to cause an application
    to crash when a specially crafted PNG image is processed

  - CAN-2004-0599

    Multiple integer overflows in the png_handle_sPLT(),
    png_read_png() functions and elsewhere could be
    exploited to cause an application to crash, or
    potentially arbitrary code to be executed, when a
    specially crafted PNG image is processed

  In addition, a bug related to CAN-2002-1363 was fixed :

  - CAN-2004-0768

    A buffer overflow could be caused by incorrect
    calculation of buffer offsets, possibly leading to the
    execution of arbitrary code"
