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.
