A vulnerability has been identified in Gentoo, which could be exploited by local attackers to potentially obtain elevated privileges. This issue is caused by an error in several ebuilds (e.g. "sys-apps/portage", "net-mail/fetchmail" or "app-editors/leo") that execute Python using "python -c", which includes the current working directory in Python's module search path, which could be exploited by malicious users to execute arbitrary code by tricking a user into running a vulnerable application in a directory containing a specially crafted module.
