Name of the Vulnerable Software and Affected Versions GNU Guix version 1.0.1

Description The issue allows local users to gain access to an arbitrary user's account. This is because the parent directory of the user-profile directories is world writable, which poses a security risk.

Recommendations For GNU Guix version 1.0.1, consider changing the permissions of the parent directory of the user-profile directories to prevent it from being world writable as a temporary mitigation measure. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
