 desc = 'The remote host is affected by the vulnerability described in GLSA-200409-12
(ImageMagick, imlib, imlib2: BMP decoding buffer overflows)


    Due to improper bounds checking, ImageMagick and imlib are vulnerable to a
    buffer overflow when decoding runlength-encoded bitmaps. This bug can be
    exploited using a specially-crafted BMP image and could potentially allow
    remote code execution when this image is decoded by the user.
  
Impact

    A specially-crafted runlength-encoded BMP could lead ImageMagick and imlib
    to crash or potentially execute arbitrary code.
  
Workaround

    There is no known workaround at this time.

Solution: 
    All ImageMagick users should upgrade to the latest version:
    # emerge sync
    # emerge -pv ">=media-gfx/imagemagick-6.0.7.1"
    # emerge ">=media-gfx/imagemagick-6.0.7.1"
    All imlib users should upgrade to the latest version:
    # emerge sync
    # emerge -pv ">=media-libs/imlib-1.9.14-r2"
    # emerge ">=media-libs/imlib-1.9.14-r2"
    All imlib2 users should upgrade to the latest version:
    # emerge sync
    # emerge -pv ">=media-libs/imlib2-1.1.2"
    # emerge ">=media-libs/imlib2-1.1.2"
