Description Pedro Sampaio 2017-07-11 14:08:31 EDT
In LibTIFF 4.0.8, there is a heap-based buffer overflow in the
t2p_write_pdf function in tools/tiff2pdf.c. This heap overflow could
lead to different damages. For example, a crafted TIFF document can
lead to an out-of-bounds read in TIFFCleanup, an invalid free in
TIFFClose or t2p_free, memory corruption in t2p_readwrite_pdf_image, or
a double free in t2p_free. Given these possibilities, it probably could
cause arbitrary code execution.
