Background
libtiff is a library that provides support for the Tag Image File Format (TIFF). It is commonly used for handling and manipulating TIFF image files. The library allows developers to read, write, and process TIFF files in various applications and programming languages. However, two vulnerabilities have been discovered in libtiff that could potentially lead to denial of service attacks or assertion failures when processing specially crafted TIFF files.
Vulnerability Detail
The first vulnerability, identified as CVE-2016-10371, involves an out-of-bounds read issue in libtiff. An attacker can exploit this vulnerability by providing a malicious TIFF file that triggers the out-of-bounds read, potentially leading to a crash or information disclosure. The second vulnerability, identified as CVE-2016-3658, is an assertion failure vulnerability.
