Subject: [FD] OpenExif multiple vulnerabilities
OpenExif multiple vulnerabilities
================
Author : qflb.wu
===============
Introduction:
=============
OpenExif is an object-oriented library for accessing Exif formatted JPEG image files. The toolkits allows for creating, reading, and modifying the metadata in the Exif file. It also provides mean of getting and setting the main image and the thumbnail image.
Affected version:
=====
2.1.4
Vulnerability Description:
==========================
1.
the ExifJpegHUFFTable::deriveTable function in src/ExifHuffmanTable.cpp in OpenExif 2.1.4 can cause a denial of service(heap-buffer-overflow and application crash) via a crafted jpg file.
./ExifTagDump openexif_2.1.4_heap_buffer_overflow_1.jpg
