 desc = 'The remote host is affected by the vulnerability described in GLSA-200501-06
(tiff: New overflows in image decoding)


    infamous41md found a potential integer overflow in the directory
    entry count routines of the TIFF library (CAN-2004-1308). Dmitry V.
    Levin found another similar issue in the tiffdump utility
    (CAN-2004-1183).
  
Impact

    A remote attacker could entice a user to view a carefully crafted
    TIFF image file, which would potentially lead to execution of arbitrary
    code with the rights of the user viewing the image. This affects any
    program that makes use of the TIFF library, including many web browsers
    or mail readers.
  
Workaround

    There is no known workaround at this time.

Solution: 
    All TIFF library users should upgrade to the latest version:
    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.7.1-r1"
  

Risk factor : Medium
