DESCRIPTION:
Two security issues have been discovered in pimd, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.
The security issues are caused due to pimd creating the
"/var/tmp/pimd.dump" and "/var/tmp/pimd.cache" files in an insecure
manner, which can be exploited to e.g. overwrite arbitrary files via
symlink attacks.
The security issues are confirmed in version 2.1.5. Other versions
may also be affected.
SOLUTION:
Restrict access to trusted users.
PROVIDED AND/OR DISCOVERED BY:
Reported to the Debian project by an unknown person.
