CVE-2018-10963 LibTIFF vulnerabilities
Title: LibTIFF vulnerabilities
Summary: LibTIFF could be made to crash or run programs as your login if it opened a
specially crafted file.
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.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2018-7456 [MEDIUM] CVE-2018-7456 libtiff: NULL pointer dereference in tif_print.c:TIFFPrintDirectory() causes a denial of service
CVE-2018-7456 libtiff: NULL pointer dereference in tif_print.c:TIFFPrintDirectory() causes a denial of service
LibTIFF through version 4.0.9 is vulnerable to a NULL pointer dereference in tif_print.c:TIFFPrintDirectory(). An attacker exploit this to cause a denial of service using the tiffinfo command with a crafted TIFF image.
This is a different issue to CVE-2017-18013.
