Summary

Details

A flaw was found in libtiff. A heap-buffer overflow vulnerability exists in the tiff2pdf utility due to an integer truncation error when processing crafted BigTIFF files. An attacker can provide a specially crafted BigTIFF file, causing a 64-bit StripByteCounts value to be truncated to a 32-bit integer. This leads to an undersized memory allocation and a subsequent out-of-bounds memory copy, resulting in a crash and severe memory corruption.
