Bug 531308 – <net-misc/openvpn-2.3.6 - critical DoS vulnerability (CVE-2014-8104)

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Christian Schmidt 2014-12-01 10:47:09 UTC]

The OpenVPN dev team announced a critical security vulnerability which will be fixed in the upcoming version 2.3.6 (see link from URL field). Please update the packages when released.


Reproducible: Always

[Comment 1 Thomas Raschbacher 2014-12-01 10:55:08 UTC]

assigning bug to maintainer and CC'ing security team (hope you don't mind ;))

[Comment 2 Josh Cepek 2014-12-01 20:28:17 UTC]

The security announcement has been published earlier today at https://community.openvpn.net/openvpn/wiki/SecurityAnnouncement-97597e732b .

All that needs to happen for the ebuild is a bump to 2.3.6. Upstream source tarballs are already available at the expected locations, which the ebuild will pick up on with the new name.

An updated ebuild is of particular importance for server installations that do not require client-certificates and either do not use the tls-auth feature or provide publicly available tls-auth keys. This is especially common in many openvpn-as-a-service installations.

Version bumped 2.3.6, okay to stabilize.

[Comment 11 Daniel "Fremen" Llewellyn 2014-12-03 12:48:09 UTC]

per my duplicate bug #531526, I suggest issuing a GLSA for <net-misc/openvpn-2.3.6 to ensure that server installations get updated post-haste.
