Background
Bitnami Golang is an open-source programming language that provides a robust development environment for building efficient and scalable applications. The compress/gzip package in Bitnami Golang is responsible for handling gzip-compressed files. It allows developers to read and write compressed files using the gzip format. However, a vulnerability has been discovered in versions before Go 1.17.12 and Go 1.18.4, which can lead to a panic due to stack exhaustion when processing an archive containing a large number of concatenated 0-length compressed files.
Vulnerability Detail
The vulnerability (CVE-2022-30631) in the compress/gzip package of Bitnami Golang arises from uncontrolled recursion in the Reader.Read function. An attacker can exploit this vulnerability by creating an archive with numerous concatenated 0-length compressed files. When the affected code attempts to read these files, it enters an uncontrolled recursion loop, causing a stack exhaustion and resulting in a panic. This vulnerability can be exploited remotely without authentication, potentially leading to a denial-of-service (DoS) condition. The severity of this vulnerability is rated as high (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
