Hence, following scenarios might happen -and trigger the NULL pointer dereference: - -(1) TIFF File of photometric type 4 or more has illegal Transfer - Function field. - -(2) TIFF File has photometric type 3 or less and defines a - SamplesPerPixel field such that SamplesPerPixel > Color Channels - without defining all extra samples in the ExtraSamples fields. - -In this patch, we address both issues with respect of the following -principles: - -(A) In the case of (1), the defined transfer table should be printed - safely even if it isn't 'legal'. This allows us to avoid expensive - checks in TIFFPrintDirectory. Also, it is quite possible that - an alternative photometric type would be developed (not part of the - standard) and would allow definition of Transfer Table. We want - libtiff to be able to handle this scenario out of the box. - -(B) In the case of (2), the transfer table should be printed at its - right size, that is if TIFF file has photometric type Palette - then the transfer table should have one row and not three, even - if two extra samples are declared. - -In order to fulfill (A) we simply add a new 'i < 3' end condition to -the broken TIFFPrintDirectory loop. This makes sure that in any case -where (b) would be respected but not (a), everything stays fine. - -(B) is fulfilled by the loop condition -'i < td->td_samplesperpixel - td->td_extrasamples'. This is enough as -long as (b) is respected. - -Naturally, we also make sure (b) is respected.
