Modification date: 17 Jan 2021
Type: security
Affected Mageia releases : 7
CVE: CVE-2018-1063

Description

Context relabeling of filesystems is vulnerable to symbolic link attack,
allowing a local, unprivileged malicious entity to change the SELinux context
of an arbitrary file to a context with few restrictions. This only happens when
the relabeling process is done, usually when taking SELinux state from disabled
to enable (permissive or enforcing) (CVE-2018-1063).
