Arch Linux Security Advisory ASA-201705-11
Date : 2017-05-10
CVE-ID : CVE-2017-8849
Package : smb4k
Type : privilege escalation
Remote : No
Link : https://security.archlinux.org/AVG-268
The package smb4k before version 2.0.0-2 is vulnerable to privilege
Upgrade to 2.0.0-2.
# pacman -Syu "smb4k>=2.0.0-2"
The problem has been fixed upstream but no release is available yet.
Smb4k <= 2.0.0 contains a logic flaw in which mount helper binary does
not properly verify the mount command it is being asked to run. This
allows calling any other binary as root since the mount helper is
typically installed as suid.
A local, unprivileged attacker can escalate privileges to become root
on the affected host.
