CVE-2014-8130: Apple iPhone OS

Medium severity, CVSS 6.5. EPSS: 3.8% chance of exploitation in the next 30 days.

The _TIFFmalloc function in tif_unix.c in LibTIFF 4.0.3 does not reject a zero size, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image that is mishandled by the TIFFWriteScanline function in tif_write.c, as demonstrated by tiffdither.
