Arch Linux Security Advisory ASA-201705-20
Date : 2017-05-22
CVE-ID : CVE-2017-8108
Package : lynis
Type : arbitrary file overwrite
Remote : No
Link : https://security.archlinux.org/AVG-278
The package lynis before version 2.5.0-1 is vulnerable to arbitrary
Upgrade to 2.5.0-1.
# pacman -Syu "lynis>=2.5.0-1"
The problem has been fixed upstream in version 2.5.0.
Michael Scherer discovered that some Lynis tests reuse the same
temporary file. As some tests remove the temporary file, this might
give an attacker the possibility to perform a link following attack.
While timing must be perfect, there is a very small time window in
which the attack can recreate the temporary file and symlink it to
another resource, like a file. In this case data may be overwritten, or
A local unprivileged attacker is able to overwrite arbitrary files on
the filesystem possibly leading to privilege escalation.
