Background
s3ql is a file system for online data storage. It provides a way to store data on various online storage services, such as Amazon S3, Google Cloud Storage, and OpenStack Swift. The package is written in Python and utilizes the pickle functionality of the language for serialization and deserialization of objects. This vulnerability in s3ql arises from the unsafe usage of the pickle functionality, which can allow a malicious storage backend or a man-in-the-middle attacker to execute arbitrary code.
Vulnerability Detail
The vulnerability in s3ql is due to the insecure implementation of the pickle functionality in Python. By exploiting this flaw, an attacker with control over the storage backend or in a man-in-the-middle position can craft malicious pickle objects that, when deserialized by s3ql, execute arbitrary code on the system. This can lead to remote code execution and potential compromise of the host system. The vulnerability has been assigned CVE-2014-0485.
