NixOS vulnerability analysis and mitigation
Overview
The vulnerability CVE-2019-18182 affects pacman versions before 5.2.0 and involves arbitrary command injection in the download_with_xfercommand() function within conf.c. This security flaw was discovered in 2019 and affects the package manager used by the Arch Linux distribution (NVD, CVE).
Technical details
The vulnerability exists in the download_with_xfercommand() function located in conf.c. It can be exploited when unsigned databases are used. To successfully exploit the vulnerability, a user must enable a non-default XferCommand and retrieve an attacker-controlled crafted database and package (NVD).
Impact
The vulnerability allows attackers to perform arbitrary command injection, which could lead to execution of malicious commands on the affected system. This is particularly concerning as pacman runs with elevated privileges as a package manager (NVD).
Mitigation and workarounds
The vulnerability was fixed in pacman version 5.2.0. Users are advised to upgrade to this version or later. The fix was also backported to various distributions, including Fedora, which addressed it in version 5.2.1 (Fedora Update).
