Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200804-11
(policyd-weight: Insecure temporary file creation)

Chris Howells reported that policyd-weight creates and uses the
'/tmp/.policyd-weight/' directory in an insecure manner.

Impact :

A local attacker could exploit this vulnerability to delete arbitrary
files or change the ownership to the 'polw' user via symlink attacks.

Workaround :

Set '$LOCKPATH = '/var/run/policyd-weight/'' manually in
'/etc/policyd-weight.conf'.

Solution :

All policyd-weight users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=mail-filter/policyd-weight-0.1.14.17'
This version changes the default path for sockets to
'/var/run/policyd-weight', which is only writable by a privileged user.
Users need to restart policyd-weight immediately after the upgrade due
to this change.

Risk factor :

Low / CVSS Base Score : 3.3
