Background
python-imaging is a Python library used for loading and manipulating image files. It provides various functionalities for image processing and editing. However, a vulnerability has been discovered in python-imaging that allows for buffer overflow attacks. Buffer overflow occurs when a program writes data beyond the allocated buffer, leading to potential code execution or system compromise.
Vulnerability Detail
The vulnerability in python-imaging is caused by two buffer overflow issues. The first buffer overflow, identified as CVE-2016-0775, is located in the FliDecode.c file. The second buffer overflow, which has not been assigned a CVE identifier yet, is found in the PcdDecode.c file. These buffer overflows can be exploited by an attacker to execute arbitrary code on the affected system. This could result in unauthorized access, data leakage, or further compromise of the system.
