Description
pacman before 5.2 is vulnerable to arbitrary command injection in src/pacman/conf.c in the download_with_xfercommand() function. This can be exploited when unsigned databases are used. To exploit the vulnerability, the user must enable a non-default XferCommand and retrieve an attacker-controlled crafted database and package.
