The TIFFReadDirEntryArray function in tif_read.c in LibTIFF 4.0.8 mishandles memory allocation for short files, which allows remote attackers to cause a denial of service (allocation failure and application crash) in the TIFFFetchStripThing function in tif_dirread.c during a tiff2pdf invocation.
La función TIFFReadDirEntryArray en tif_read.c en LibTIFF 4.0.8 maneja incorrectamente la asignación de memoria para archivos pequeños, lo que permite a los atacantes remotos provocar una denegación de servicio en la función TIFFFetchStripThing en tif_dirread.c durante una invocación tiff2pdf.
It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
