Bodhi update submission link: https://admin.fedoraproject.org/updates/new/?type_=security&bugs=960192,960195 openvpn-2.3.1-1.el5 has been submitted as an update for Fedora EPEL 5. https://admin.fedoraproject.org/updates/openvpn-2.3.1-1.el5 Package openvpn-2.3.1-1.el5: * should fix your issue, * was pushed to the Fedora EPEL 5 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=epel-testing openvpn-2.3.1-1.el5' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-EPEL-2013-5711/openvpn-2.3.1-1.el5 then log in and leave karma (feedback). openvpn-2.3.1-1.el5 has been pushed to the Fedora EPEL 5 stable repository. If problems still persist, please make note of it in this bug report. Got this update last night. It looks like in 2.3.1, existing route scripts break when they just say, e.g.:
route add -net 172.16.0.0 netmask 255.240.0.0 gw $5
with error:
/etc/openvpn/hq-routes.up tun0 1500 1545 172.16.1.2 172.16.1.1 init
WARNING: Failed running command (--up/--down): could not execute external program
Exiting due to fatal error
The workaround being to fully path 'route' as '/sbin/route'. Fully pathing isn't a bad idea, but most of the documentation out there looks like the plain 'route' line.
I looked at the openvpn changelog and don't see this being listed as purposeful, except for:
env_block(): if PATH is not set, add standard PATH setting to env
but that seems to be for win32.c, though maybe a global change made it necessary to fix on win32 and nobody noticed on unix yet.
