Subject: Re: CVE Request -- Four (stack-based) buffer
overflows and one use-after-free in libtiff v4.0.3 reported by Pedro

Hello vendors,
since Kurt asked for it, below is the summary of the issues.

> Hello Kurt, Steve, vendors,

> Pedro Ribeiro has recently reported the following five security

> [1] http://www.asmail.be/msg0055359936.html
* Issue #1 (tools/gif2tiff.c): Stack-based buffer overflow in the gif2tiff tool when reading GIF extension block on crafted GIF image
* Issue #2 (tools/gif2tiff.c): Stack-based buffer overflow in the gif2tiff tool when decoding a GIF raster image
* Issue #3 (tools/gif2tiff.c): Stack-based buffer overflow in the gif2tiff tool when decoding a GIF raster image (same routine like
in case #2, just different line code)
* Issue #4 (tools/tiff2pdf.c): Use after free in tiff2pdf tool when reading TIFF file raster image data and writing them to the output PDF XObject's
image dictionary stream
* Issue #5 (tools/rgb2ycbcr.c): Stack-based buffer overflow in the rgb2ycbcr tool when performing RGBA to YCbCr conversion (converting
non-YCbCr TIFF image to a YCbCr one) when processing crafted rasted date of provided TIFF image file
Thank you && Regards, Jan.
