Background
The Tag Image File Format (TIFF) library is a widely used open-source library for reading and writing image files. It provides support for various image formats and is commonly used in applications that deal with images. However, several vulnerabilities have been discovered in the TIFF library and its associated tools.
Vulnerability Detail
One of the vulnerabilities, identified as CVE-2017-11335, is a heap-based buffer overflow that occurs when processing a PlanarConfig=Contig image. This vulnerability can be exploited by an attacker to trigger an out-of-bounds write, leading to a remote denial of service attack or arbitrary code execution. Another vulnerability, CVE-2017-12944, involves a mishandling of memory allocation for short files, which can result in a denial of service (allocation failure and application crash) during a tiff2pdf invocation. Additionally, there are two vulnerabilities, CVE-2017-13726 and CVE-2017-13727, that allow a crafted input to cause a reachable assertion abort, leading to a remote denial of service attack.
